Two very simple examples of using the Coordinator/KS mechanism:
they both schedule real time alarms and listen to the keyboard
and echo any input.

The first (example) puts the results to the standard output
(i.e. the terminal where the program was started).

The second (xexample) uses the Motif widget set to pop-up
a window and puts the results in there. It essentially demonstrates
that the OSIMIS coordinating mechanism can pass control to that of Motif
through the XCoordinator class.

The second (tkexample) uses the TK widget set to pop-up
a window and puts the results in there. It essentially demonstrates
that the OSIMIS coordinating mechanism can pass control to that of TCL/TK
through the TkCoordinator class.
