The idea here is to simulate the layerswitcher radiobuttons UI
without all the overhead of openlayers.
There are event handlers attached to the following elements:
* Body - Prints message "clicked body" to message area
* Blue Div - Prints message "clicked div" to message area, stops
the event propagation, prints a message with the
status of the two radiobuttons
* Radio One - Prints message "clicked one" to message area
* Radio Two - Prints message "clicked two" to message area
The problem, as you will see if you click the radio buttons
themselves, is that their "checked" status seems to update, but
their visual UI bit does not. Can we fix this!?!
