// Description...: Global function used by the RSES library.
// Comments......: Excerpt from the RSES library technical documentation:
//
//                   It has to be written the definition of function
//                   void Message(char *text, char *status) that is
//                   used by some methods to give description what is
//                   actually being done. This function is called in
//                   many different ways:
//
//                   text NOT NULL, status NULL: it is general
//                   description about what is being done e.g.
//                   "Calculating reducts".
//
//                   text NOT NULL, status NOT NULL: more descriptive
//                   information with additional information about
//                   kind of progress of performed operation e.g.
//                   text="Found reducts:", status="20".
//
//                   text NULL, status NOT NULL: the information about
//                   progress is passed only e.g. "17%".
//
//                   According to the needs function Message may take
//                   advantage of passed information. It may display
//                   messages in different windows, etc.
//
//                   This function may additionally control the predefined
//                   variable MESSAGE_LEVEL that is used to filter the
//                   passed information. It is made the assumption that
//                   (1) MESSAGE_LEVEL=0 means that none information is displayed,
//                   (2) MESSAGE_LEVEL=1 means that all information is displayed.
//                   It can be implemented that for example if MESSAGE_LEVEL=2
//                   then only status variable is displayed and if MESSAGE_LEVEL=3
//                   than only the character
