Michael Goddard 4d13a15bae Clarify API/docs by introducing the audio "frame", and add helpers.
The frame is the interleaved set of one sample for each channel.  Add
some docs and some methods that make working with samples a bit more
convenient.

Adjusted QAudioBuffer to use these helper functions and terminology.
