* 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.
