    File:       rc_std.js

    Purpose:    Provides standard functionality available for all
                successive javascripts.

    Remarks:    Present support:

                    1. Presently out-of-date browser sniffer.
                    2. debug-mode variable that probably should not be in here,
                       since I have to edit this file to turn it on and off.
