+*  A base class for listening card events.
+*  This class is a virtual base class used to transmit card events from 
+*  a spesific reader to the terminal, and it intended for use in all 
+*  applications that need to use smart cards. When an event occurs, 
+*  it is reported to the listener, and the listener will launch the 
+*  ProcessEvent function. This function is pure virtual, so a user of 
+*  this class must derive a concrete class from CScardListener, 
+*  and give an implementation to the ProcessEvent function.
