    Mimic VB's GetObject() function.

    connect to an already running instance of the COM object.

    ob = GetObject(r"c:\blah\blah\foo.xls") (aka the COM moniker syntax)
    will return a ready to use Python wrapping of the required COM object.

    Note: You must specifiy one or the other of these arguments. I know
    this isn't pretty, but it is what VB does. Blech. If you don't
    I'll throw ValueError at you. :)

    This will most likely throw pythoncom.com_error if anything fails.
