//  ESAF Message Source
//  ===================
//
//  Each class that wants to send messages must inherit from this one
//
//  Two ways to send a message:
//  
//  Using a stream
//  examples (equivalent):
//     Msg(EsafMsg::Warning) << "my text" << MsgDispatch;
//  or
//     Msg(EsafMsg::Warning) << "my text";
//     Dispatch();
//
//  or using printf like syntax:
//  example:
//     MsgForm( EsafMsg::Severity, "msg with printf formatting", var1, var2...);
//  
//  The messages are dispatched on screen and log file according to the default
//  values specified by the configuration files
//
//BEGIN_HTML <!--
/* -->
<!--*/
// -->END_HTML
