Wav file tone generation library.

[agraham]

Unlike some versions of Basic Basic4PPC does not implement a Beep statement that can specify the frequency and duration of a tone. These libraries, one each for desktop and device, let you write a wav file of the required frequency and duration. They also provide playback of any wav file with some additional options not available to the Basic4PPC Sound facility.

I knocked these libraries up for a specific use in another thread but thought that I would post them here complete with demo app and help file in case they are of use to anyone else.
