A new Tcl/tk example - a window to show system status

From today's Tcl course - where we have also added a GUI on the front using Tk to give a window in which we display system information.

The code is divided into a number of sections

1. Definition of pieces of code to be run in the event of a button being pushed, or some other action

2. Creation of the widgets (components) to be shown

3. Packing those components into a geometry

4. Processing the event code initially (to pretend that initial buttons had been pressed)

5. Finally, the code enters a main loop to wait for events and process them as it receives them.
