   $DESCRIPTION$
      A good way to display information messages during the running
      of an application is to send them all to the SAME line on the
      screen where users are expected to look for them. In order to
      give users a chance to read the current message before the next one
      is displayed we may need to insert a delay after each message.

      ft_Pending() function displays messages by keeping track of
      the time of the last message and providing a delay ONLY if the next
      pending message is issued much too soon after the current one.

   $EXAMPLES$
      ft_Pending( "Message one", 20, 0, 3, "W+/G" ) // Displays "Message one."
                                                    // sets row to 20, col to 0.
                                                    // wait to 3 and color to
                                                    // bright white over green.
      ft_Pending( "Message two" )   // Displays "Message two", after 5 sec.
      ft_Pending( "Message three" ) // Displays "Message three", after 5 sec.


      // Note that default row, col, wait time and color need to be set only
      // once in the very first call to ft_Pending() and only if the internal
      // default values are not appropriate.
