// Details:	MI debug utility class. Used to indicate the current function
//			depth in the call stack. It uses the CMIlCmnLog logger to output
//			the current fn trace information.
//			Use macro MI_TRACEFN( "Some fn name" ) and implement the scope of
//			the functions you wish to build up a trace off.
//			Use preprocessor definition MI_USE_DEBUG_TRACE_FN to turn off or on
//			tracing code.
// Gotchas:	None.
