Fixed CIM debacle

//
//
// This header describes the cimmofParser class.  
// It is a singleton, and can only be accessed via the pointer
// returned by its static Intance() method.
// //
// The instance of this
// class hold enough state information that there should be no need for
// the underlying YACC parser to be written reentrant.
//
// The YACCer (and LExer) communicate with the instance of this class
// via the ointer returned by the Instance() method.
//
// This specialization contains a reference to the containing program's
// mofComplerCmdLine object, which holds the command line arguments
// including the list of directories to search to find included mof files
//
