CCmdTraget has the implementation of the Message map.
Message map routes the commands & messages to the member
functions you write to handle them. Key frame work classes
derived from the CCmdtarget includes CWnd, Cview etc..
If you need new user class handel the messages, derive the
class from any of the class which are derived from
CCmdTarget.

Answer / abhijit
* It is the base class for MFC's message map architecture
* Message map functionality is given through its virtual
member function OnCmdMsg
*** Owing to the way message map architecture is
implemented there is no provision for multiple inheritance
in MFC (1 window can not have two parents ... if the
derived class cant handle a message... and both parents
can... which parent should handle!!!)
