An interface to a set of audio player callback functions.

The class is a mixin and is intended to be inherited by the client
class which is observing the audio playing operation. The functions
encapsulated by this class are called when specific events occur in
the process of initialising and playing an audio sample. A reference to
this object is passed as a parameter when constructing an audio player
utility object.

/**

Plays sampled audio data.

The class offers a simple interface to open, play and obtain
information from, sampled audio data. The audio data can be supplied
either in a file (file-based), as a descriptor
(descriptor-based) or as a URL reference (since version 7.0s).

While this class is abstract, the three static functions construct, initialise
and return pointers to instances of concrete classes derived from this
abstract class.
