* Description:  Declaration for CBTSAController class. This class is advertised

*				 to E-com framework (@see proxy.cpp) so that it loads this class when 

*				 this plugin gets loaded. That is why this class implements the interface

*				 of the module (currently BT Accessory Server) which loads this plugin. Being

*				 main class, this class constructs other classes and also recieves callbacks,

*				 hence implementing their interfaces.
