+   *
+   * @description
+   * Resolves a set of invocables. An invocable is a function to be invoked via 
+   * `$injector.invoke()`, and can have an arbitrary number of dependencies. 
+   * An invocable can either return a value directly,
+   * or a `$q` promise. If a promise is returned it will be resolved and the 
+   * resulting value will be used instead. Dependencies of invocables are resolved 
+   * (in this order of precedence)
+   *
+   * - from the specified `locals`
+   * - from another invocable that is part of this `$resolve` call
+   * - from an invocable that is inherited from a `parent` call to `$resolve` 
+   *   (or recursively
+   * - from any ancestor `$resolve` of that parent).
+   *
+   * The return value of `$resolve` is a promise for an object that contains 
+   * (in this order of precedence)
+   *
+   * - any `locals` (if specified)
+   * - the resolved return values of all injectables
+   * - any values inherited from a `parent` call to `$resolve` (if specified)
+   *
+   * The promise will resolve after the `parent` promise (if any) and all promises 
+   * returned by injectables have been resolved. If any invocable 
+   * (or `$injector.invoke`) throws an exception, or if a promise returned by an 
+   * invocable is rejected, the `$resolve` promise is immediately rejected with the 
+   * same error. A rejection of a `parent` promise (if specified) will likewise be 
+   * propagated immediately. Once the `$resolve` promise has been rejected, no 
+   * further invocables will be called.
+   * 
+   * Cyclic dependencies between invocables are not permitted and will cause `$resolve`
+   * to throw an error. As a special case, an injectable can depend on a parameter 
+   * with the same name as the injectable, which will be fulfilled from the `parent` 
+   * injectable of the same name. This allows inherited values to be decorated. 
+   * Note that in this case any other injectable in the same `$resolve` with the same
+   * dependency would see the decorated value, not the inherited value.
+   *
+   * Note that missing dependencies -- unlike cyclic dependencies -- will cause an 
+   * (asynchronous) rejection of the `$resolve` promise rather than a (synchronous) 
+   * exception.
+   *
+   * Invocables are invoked eagerly as soon as all dependencies are available. 
+   * This is true even for dependencies inherited from a `parent` call to `$resolve`.
+   *
+   * As a special case, an invocable can be a string, in which case it is taken to 
+   * be a service name to be passed to `$injector.get()`. This is supported primarily 
+   * for backwards-compatibility with the `resolve` property of `$routeProvider`

+   * `$injector` services to fetch.
+   * @param {object} locals  values to make available to the injectables

+   * @param {object} self  the `this` for the invoked methods

+/**
+ * @ngdoc object
+ * @name ui.router.util.type:UrlMatcher
+ *
+ * @description
+ * Matches URLs against patterns and extracts named parameters from the path or the search
+ * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
+ * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
+ * do not influence whether or not a URL is matched, but their values are passed through into
+ * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
+ *
+ * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
+ * syntax, which optionally allows a regular expression for the parameter to be specified:
+ *
+ * * `':'` name - colon placeholder
+ * * `'*'` name - catch-all placeholder
+ * * `'{' name '}'` - curly placeholder
+ * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
+ *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
+ *
+ * Parameter names may contain only word characters (latin letters, digits, and underscore) and
+ * must be unique within the pattern (across both path and search parameters). For colon
+ * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
+ * number of characters other than '/'. For catch-all placeholders the path parameter matches
+ * any number of characters.
+ *
+ * Examples:
+ *
+ * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
+ *   trailing slashes, and patterns have to match the entire path, not just a prefix.
+ * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
+ *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
+ * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
+ * * `'/user/{id:[^/]*}'` - Same as the previous example.
+ * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
+ *   parameter consists of 1 to 8 hex digits.
+ * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
+ *   path into the parameter 'path'.
+ * * `'/files/*path'` - ditto.
+ * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
+ *   in the built-in  `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
+ *
+ * @param {string} pattern  The pattern to compile into a matcher.
+ * @param {Object} config  A configuration object hash:
+ * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
+ *   an existing UrlMatcher
+ *
+ * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
+ * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
+ *
+ * @property {string} prefix  A static prefix of this pattern. The matcher guarantees that any
+ *   URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
+ *   non-null) will start with this prefix.
+ *
+ * @property {string} source  The pattern that was passed into the constructor
+ *
+ * @property {string} sourcePath  The path portion of the source property
+ *
+ * @property {string} sourceSearch  The search portion of the source property
+ *
+ * @property {string} regex  The constructed regex that will be used to match against the url when
+ *   it is time to determine which url will match.
+ *
+ * @returns {Object}  New `UrlMatcher` object

+   * $state.go('list', { item: "Ringo" });
+   * </pre>

+   *     post: Posts
+   *   };

+   *   return {
+   *     encode: function(object) {
+   *       // Represent the object in the URL using its unique ID

+   *     },
+   *     decode: function(value, key) {
+   *       // Look up the object by ID, using the parameter
+   *       // name (key) to call the correct service
+   *       return services[key].findById(value);
+   *     },
+   *     is: function(object, key) {
+   *       // Check that object is a valid dbObject
+   *       return angular.isObject(object) && object.id && services[key];
+   *     }
+   *     equals: function(a, b) {
+   *       // Check the equality of decoded objects by comparing

+   * @ngdoc function
+   * @name ui.router.state.$stateProvider#decorator
+   * @methodOf ui.router.state.$stateProvider
+   *
+   * @description
+   * Allows you to extend (carefully) or override (at your own peril) the 
+   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
+   * to add custom functionality to ui-router, for example inferring templateUrl 
+   * based on the state name.
+   *
+   * When passing only a name, it returns the current (original or decorated) builder
+   * function that matches `name`.
+   *
+   * The builder functions that can be decorated are listed below. Though not all
+   * necessarily have a good use case for decoration, that is up to you to decide.
+   *
+   * In addition, users can attach custom decorators, which will generate new 
+   * properties within the state's internal definition. There is currently no clear 
+   * use-case for this beyond accessing internal states (i.e. $state.$current), 
+   * however, expect this to become increasingly relevant as we introduce additional 
+   * meta-programming features.
+   *
+   * **Warning**: Decorators should not be interdependent because the order of 
+   * execution of the builder functions in non-deterministic. Builder functions 
+   * should only be dependent on the state definition object and super function.
+   *
+   *
+   * Existing builder functions and current return values:
+   *
+   * - **parent** `{object}` - returns the parent state object.
+   * - **data** `{object}` - returns state data, including any inherited data that is not
+   *   overridden by own values (if any).
+   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
+   *   or `null`.
+   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
+   *   navigable).
+   * - **params** `{object}` - returns an array of state params that are ensured to 
+   *   be a super-set of parent's params.
+   * - **views** `{object}` - returns a views object where each key is an absolute view 
+   *   name (i.e. "viewName@stateName") and each value is the config object 
+   *   (template, controller) for the view. Even when you don't use the views object 
+   *   explicitly on a state config, one is still created for you internally.
+   *   So by decorating this builder function you have access to decorating template 
+   *   and controller properties.
+   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
+   *   not including any params defined by ancestor states.
+   * - **path** `{string}` - returns the full path from the root down to this state. 
+   *   Needed for state activation.
+   * - **includes** `{object}` - returns an object that includes every state that 
+   *   would pass a `$state.includes()` test.
+   *

+   * </pre>
+   *
+   * @param {object=} stateConfig.views
+   * <a id='views'></a>
+   * an optional map&lt;string, object&gt; which defined multiple views, or targets views
+   * manually/explicitly.
+   *
+   * Examples:
+   *
+   * Targets three named `ui-view`s in the parent state's template
+   * <pre>views: {
+   *     header: {
+   *       controller: "headerCtrl",

+   *       templateUrl: "footer.html"
+   *     }
+   *   }</pre>
+   *
+   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
+   * <pre>views: {
+   *     'header@top': {

+   *     }
+   *   }</pre>
+   *
+   * @param {boolean=} [stateConfig.abstract=false]
+   * <a id='abstract'></a>
+   * An abstract state will never be directly activated,

+   * <pre>abstract: true</pre>
+   *
+   * @param {function=} stateConfig.onEnter
+   * <a id='onEnter'></a>
+   *
+   * Callback function for when a state is entered. Good way
+   *   to trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explicitly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * <pre>onEnter: function(MyService, $stateParams) {
+   *     MyService.foo($stateParams.myParam);
+   * }</pre>
+   *
+   * @param {function=} stateConfig.onExit
+   * <a id='onExit'></a>
+   *
+   * Callback function for when a state is exited. Good way to
+   *   trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explicitly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * <pre>onExit: function(MyService, $stateParams) {
+   *     MyService.cleanup($stateParams.myParam);
+   * }</pre>
+   *
+   * @param {boolean=} [stateConfig.reloadOnSearch=true]
+   * <a id='reloadOnSearch'></a>
+   *
+   * If `false`, will not retrigger the same state
+   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
+   *   Useful for when you'd like to modify $location.search() without triggering a reload.
+   * <pre>reloadOnSearch: false</pre>
+   *
+   * @param {object=} stateConfig.data
+   * <a id='data'></a>
+   *
+   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
+   *   prototypally inherited.  In other words, adding a data property to a state adds it to
+   *   the entire subtree via prototypal inheritance.
+   *
+   * <pre>data: {
+   *     requiredRole: 'foo'
+   * } </pre>
+   *
+   * @param {object=} stateConfig.params
+   * <a id='params'></a>
+   *
+   * A map which optionally configures parameters declared in the `url`, or
+   *   defines additional non-url parameters.  For each parameter being
+   *   configured, add a configuration object keyed to the name of the parameter.
+   *
+   *   Each parameter configuration object may contain the following properties:
+   *
+   *   - ** value ** - {object|function=}: specifies the default value for this
+   *     parameter.  This implicitly sets this parameter as optional.
+   *
+   *     When UI-Router routes to a state and no value is
+   *     specified for this parameter in the URL or transition, the
+   *     default value will be used instead.  If `value` is a function,
+   *     it will be injected and invoked, and the return value used.
+   *
+   *     *Note*: `undefined` is treated as "no default value" while `null`
+   *     is treated as "the default value is `null`".
+   *
+   *     *Shorthand*: If you only need to configure the default value of the
+   *     parameter, you may use a shorthand syntax.   In the **`params`**
+   *     map, instead mapping the param name to a full parameter configuration
+   *     object, simply set map it to the default parameter value, e.g.:
+   *
+   * <pre>// define a parameter's default value
+   * params: {
+   *     param1: { value: "defaultValue" }
+   * }
+   * // shorthand default values
+   * params: {
+   *     param1: "defaultValue",
+   *     param2: "param2Default"

+   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter

+   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
+   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
+   *     configured default squash policy.
+   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
+   *
+   *   There are three squash settings:
+   *
+   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
+   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
+   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
+   *       This can allow for cleaner looking URLs.
+   *     - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
+   *
+   * <pre>params: {
+   *     param1: {
+   *       value: "defaultId",
+   *       squash: true

+     * - `$state.go('.child.grandchild')` - will go to grandchild state
+     *
+     * @param {object=} params A map of the parameters that will be sent to the state, 
+     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
+     * defined parameters. Only parameters specified in the state definition can be overridden, new 
+     * parameters will be ignored. This allows, for example, going to a sibling state that shares parameters
+     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
+     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
+     * will get you all current parameters, etc.
+     * @param {object=} options Options object. The options are:
+     *
+     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
+     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
+     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
+     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
+     *    defines which state to be relative from.
+     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
+     * - **`reload`** (v0.2.5) - {boolean=false|string|object}, If `true` will force transition even if no state or params
+     *    have changed.  It will reload the resolves and views of the current state and parent states.
+     *    If `reload` is a string (or state object), the state object is fetched (by name, or object reference); and \
+     *    the transition reloads the resolves and views for that matched state, and all its children states.
+     *
+     * @returns {promise} A promise representing the state of the new transition.
+     *
+     * Possible success values:
+     *
+     * - $state.current
+     *
+     * <br/>Possible rejection values:

+     * - 'transition superseded' - when a newer transition has been started after this one

+/**
+ * @ngdoc directive
+ * @name ui.router.state.directive:ui-view
+ *
+ * @requires ui.router.state.$state
+ * @requires $compile
+ * @requires $controller
+ * @requires $injector
+ * @requires ui.router.state.$uiViewScroll
+ * @requires $document
+ *
+ * @restrict ECA
+ *
+ * @description
+ * The ui-view directive tells $state where to place your templates.
+ *
+ * @param {string=} name A view name. The name should be unique amongst the other views in the
+ * same state. You can have views of the same name that live in different states.
+ *
+ * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
+ * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
+ * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
+ * scroll ui-view elements into view when they are populated during a state activation.
+ *
+ * @param {string=} noanimation If truthy, the non-animated renderer will be selected (no animations
+ * will be applied to the ui-view)
+ *
+ * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
+ * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
+ *
+ * @param {string=} onload Expression to evaluate whenever the view updates.
+ * 
+ * @example
+ * A view can be unnamed or named. 
+ * <pre>
+ * <!-- Unnamed -->
+ * <div ui-view></div> 
+ * 
+ * <!-- Named -->
+ * <div ui-view="viewName"></div>
+ * </pre>
+ *
+ * You can only have one unnamed view within any template (or root html). If you are only using a 
+ * single view and it is unnamed then you can populate it like so:
+ * <pre>
+ * <div ui-view></div> 
+ * $stateProvider.state("home", {
+ *   template: "<h1>HELLO!</h1>"
+ * })
+ * </pre>
+ * 
+ * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#views `views`}
+ * config property, by name, in this case an empty name:
+ * <pre>
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "<h1>HELLO!</h1>"
+ *     }
+ *   }    
+ * })
+ * </pre>
+ * 
+ * But typically you'll only use the views property if you name your view or have more than one view 
+ * in the same template. There's not really a compelling reason to name a view if its the only one, 
+ * but you could if you wanted, like so:
+ * <pre>
+ * <div ui-view="main"></div>
+ * </pre> 
+ * <pre>
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "main": {
+ *       template: "<h1>HELLO!</h1>"
+ *     }
+ *   }    
+ * })
+ * </pre>
+ * 
+ * Really though, you'll use views to set up multiple views:
+ * <pre>
+ * <div ui-view></div>
+ * <div ui-view="chart"></div> 
+ * <div ui-view="data"></div> 
+ * </pre>
+ * 
+ * <pre>
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "<h1>HELLO!</h1>"
+ *     },
+ *     "chart": {
+ *       template: "<chart_thing/>"
+ *     },
+ *     "data": {
+ *       template: "<data_thing/>"
+ *     }
+ *   }    
+ * })
+ * </pre>
+ *
+ * Examples for `autoscroll`:
+ *
+ * <pre>
+ * <!-- If autoscroll present with no expression,
+ *      then scroll ui-view into view -->
+ * <ui-view autoscroll/>
+ *
+ * <!-- If autoscroll present with valid expression,
+ *      then scroll ui-view into view if expression evaluates to true -->
+ * <ui-view autoscroll='true'/>
+ * <ui-view autoscroll='false'/>
+ * <ui-view autoscroll='scopeVariable'/>
+ * </pre>

+ * @restrict A
+ *
+ * @description
+ * A directive that binds a link (`<a>` tag) to a state. If the state has an associated
+ * URL, the directive will automatically generate & update the `href` attribute via
+ * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
+ * the link will trigger a state transition with optional parameters.
+ *
+ * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
+ * handled natively by the browser.
+ *
+ * You can also use relative state paths within ui-sref, just like the relative
+ * paths passed to `$state.go()`. You just need to be aware that the path is relative
+ * to the state that the link lives in, in other words the state that loaded the
+ * template containing the link.
+ *
+ * You can specify options to pass to {@link ui.router.state.$state#go $state.go()}
+ * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
+ * and `reload`.
+ *
+ * @example
+ * Here's an example of how you'd use ui-sref and how it would compile. If you have the
+ * following template:
+ * <pre>
+ * <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
+ *
+ * <ul>
+ *     <li ng-repeat="contact in contacts">
+ *         <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
+ *     </li>
+ * </ul>
+ * </pre>
+ *
+ * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
+ * <pre>
+ * <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>

+ * related ui-sref directive's state is active, and removing them when it is inactive.
+ * The primary use-case is to simplify the special appearance of navigation menus
+ * relying on `ui-sref`, by having the "active" state's menu button appear different,
+ * distinguishing it from the inactive menu items.
+ *
+ * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
+ * ui-sref-active found at the same level or above the ui-sref will be used.
+ *
+ * Will activate when the ui-sref's target state or any child state is active. If you
+ * need to activate only when the ui-sref target state is active and *not* any of
+ * it's children, then you will use
+ * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
+ *
+ * @example
+ * Given the following template:
+ * <pre>
+ * <ul>
+ *   <li ui-sref-active="active" class="item">
+ *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
+ *   </li>
+ * </ul>
+ * </pre>
+ *
+ *
+ * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
+ * the resulting HTML will appear as (note the 'active' class):
+ * <pre>
+ * <ul>
+ *   <li ui-sref-active="active" class="item active">
+ *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
+ *   </li>
+ * </ul>
+ * </pre>
+ *
+ * The class name is interpolated **once** during the directives link time (any further changes to the
+ * interpolated value are ignored).
+ *
+ * Multiple classes may be specified in a space-separated format:
+ * <pre>
+ * <ul>
+ *   <li ui-sref-active='class1 class2 class3'>
+ *     <a ui-sref="app.user">link</a>
+ *   </li>
+ * </ul>
+ * </pre>
+ *
+ * It is also possible to pass ui-sref-active an expression that evaluates
+ * to an object hash, whose keys represent active class names and whose
+ * values represent the respective state names/globs.
+ * ui-sref-active will match if the current active state **includes** any of
+ * the specified state names/globs, even the abstract ones.
+ *
+ * @Example
+ * Given the following template, with "admin" being an abstract state:
+ * <pre>
+ * <div ui-sref-active="{'active': 'admin.*'}">
+ *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
+ * </div>
+ * </pre>
+ *
+ * When the current state is "admin.roles" the "active" class will be applied
+ * to both the <div> and <a> elements. It is important to note that the state
+ * names/globs passed to ui-sref-active shadow the state provided by ui-sref.
