Abstract base class for providing the location of audio clip data.

The location could be a filename or the address of a descriptor. An object of the derived class 

is passed as a parameter to CMdaAudioRecorderUtility::OpenL() (to record a clip) or 

CMdaAudioConvertUtility::OpenL() (to convert a clip to another format). This class could be

derived from to create new types of clip location.
