numpy). GUI related functionality is now loaded by the application code
explicitly calling the props.initGUI function, so that wx is not
implicitly imported.

When a widget built by the build module is destroyed, all references
to the callback functions/GUI objecst are explicitly cleared, as
circular references were preventing automatic garbage collection.

ColourPickerCtrl doesn't get sized properly. Boolean properties can be
displayed with a  (custom) bitmap toggle button.
