// *****************************************************************************
//
// CLASS DESCRIPTION (MArgParser)
//
// This class is used to parse and store all of the flags, arguments
// and objects which are passed to a command.  The MArgParser accepts
// an MSyntax object, which describes the format for a command, and uses
// it to parse the command arguments into a form which is easy to query.
