+*				 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.
