Develop-test-debug cycle

[logistix]

Like Tim said, the module is getting reloaded but instances aren't getting
re-instantiated.  If it's not too time-intensive, use the if
__name__=="__main__" trick in your script.

if __name__ == "__main__":
    reload(wibbleModule)
    wibs = wibble(args)
    wibs.test1()
    wibs.test2()

and just run it again from the interpreter.

If that's too slow and you want to use some really bad voodoo, you can also
modify the classes in-place:
