//	BRAHMS Analysis Module Class
//	
//	A standard IO should be derived from 
//	this base class. This ensure that the general framework
//	is capable of accessing these in a common and general way.
//	The methods (member functions) consists of a general set for
//	all modules; but the user if free to add specific ones for
//	specific needs. 
//      The initial version
//	is derived from the ROOT base classes,
//      the class share many traits with the BrModule Class but has a different
//      set of member functions.
