/** Utility class for simple sound playing.

Must be used in the same thread as an active UI Control Framework environment 
(CCoeEnv). 

This class plays the sound specified by a TBaSystemSoundType object. The 
caller can request the sound to be repeated, and the time between repeats. 
If the exact sound cannot be found on a particular device, a match only by 
category (first UID) is used. No sound will play if a match is not found.
