-/* Public: Reads a subset of bits into a uint64_t, right aligned so they may be
- * interpreted as a number.
- *
- * source - the bytes in question.
- * source_size - the number of bytes in the source.
- * offset - the starting index of the bit field (beginning from 0).
- * bit_count - the width of the bit field to extract. This must be less than or
- *      equal to 64.
- *
- * Bit fields are positioned according to big-endian bit layout and the data is
- * swapped automatically as necessary depending on the compiled architecture.
- *
- * For example, the bit layout of the value "42" (i.e. 00101010 set at position
- * 14 with length 6 is:
- *
- *     000000000000001010100000000000000000000000000000000000000000000
- *
- * and the same value and position but with length 8 is:
- *
- *     000000000000000010101000000000000000000000000000000000000000000
- *
- * Examples
- *
- *  uint64_t value = get_bitfield(data, data_size, 2, 4);
- *
- * Returns the value of the requested bit field, right aligned in a uint64_t.

- *
- * The range does not need to be byte aligned, and the source and destination do
- * not have to be the same size (as long as the desitnation has enough room to
- * fit the range).
- *
- * A bit array with regards to this function always has the leftmost bit in byte
- * 0, i.e. bit index is the leftmost bit of byte 0. Endianness does not matter.
- *
- * For example:
- *
- *      uint8_t source[4] = {0x11, 0x22, 0x33, 0x44};
- *      uint8_t destination[4] = {0};
- *      copy_bits(source, sizeof(source), 8, 8, destination,

- *      // destination[1] == 0x0
- *      // destination[2] == 0x0

- * Thanks to
- * http://stackoverflow.com/questions/3534535/whats-a-time-efficient-algorithm-to-copy-unaligned-bit-arrays
- * for the implementation of the algorithm.

- * source_origin - the source array.
- * source_length - the total length of the source array in bytes,

- * source_offset - an offset in bits to start the copy from the source array.
- *      Specify 0 to start from source_origin.
- * bit_count - the number of bits to copy.
- * destination_origin - the destination array.
- * desitnation_length - the total length of the destination array in bytes,
- *      for range checking.
- * destination_offset - an offset in bits to start placing the copied range into
- *      the destination array. Specify 0 to start from the beginning of the
- *      destination. If you are copying a range not aligned on a byte, you
- *      probably want to set this to a positive offset to right the resulting
- *      bits in the destination.
- *
- * Returns true if the copy was successful and false if the range exceeded the
- * size of the source or destination, or if the range size negative or 0.
