Change directory architecture to use 2 separated projects.
Each projects, binder and generator, has to be compiled separatly. CAN-binder will host high and low level binding CAN-config-generator only the generator used for low level binding. build.sh script just launch both build in their respective dir.

-/// @brief Add and send a new recurring diagnostic request.
-///
-/// At most one recurring request can be active for the same arbitration ID, mode
-/// and (if set) PID on the same bus at one time. If you try and call
-/// addRecurringRequest with the same key, it will return an error.
-///
-/// TODO: This also adds any neccessary CAN acceptance filters so we can receive the
-/// response. If the request is to the functional broadcast ID (0x7df) filters
-/// are added for all functional addresses (0x7e8 to 0x7f0).
-///
-/// Example:
-///
-/// // Creating a functional broadcast, mode 1 request for PID 2.
-/// DiagnosticRequest request = {
-/// arbitration_id: 0x7df,
-/// mode: 1,
-/// has_pid: true,
-/// pid: 2
-/// };
-///
-/// // Add a recurring request, to be sent at 1Hz, and published with the
-/// // name "my_pid_request"
-/// addRecurringRequest(&getConfiguration()->diagnosticsManager,
-/// canBus,
-/// &request,
-/// "my_pid_request",
-/// false,
-/// NULL,
-/// NULL,
-/// 1);
-///
-/// @param[in] request - The parameters for the request.
-/// @param[in] name - An optional human readable name this response, to be used when
-/// publishing received responses. If the name is NULL, the published output
-/// will use the raw OBD-II response format.
-/// @param[in] wait_for_multiple_responses - If false, When any response is received
-/// for this request it will be removed from the active list. If true, the
-/// request will remain active until the timeout clock expires, to allow it
-/// to receive multiple response. Functional broadcast requests will always
-/// waint for the timeout, regardless of this parameter.
-/// @param[in] decoder - An optional DiagnosticResponseDecoder to parse the payload of
-/// responses to this request. If the decoder is NULL, the output will
-/// include the raw payload instead of a parsed value.
-/// @param[in] callback - An optional DiagnosticResponseCallback to be notified whenever a
-/// response is received for this request.
-/// @param[in] frequencyHz - The frequency (in Hz) to send the request. A frequency above
-/// MAX_RECURRING_DIAGNOSTIC_FREQUENCY_HZ is not allowed, and will make this
-/// function return false.
-///
-/// @return true if the request was added successfully. Returns false if there
-/// was too much already running requests, if the frequency was too high TODO:or if the
