def register(self, *magic_objects):
        """Register one or more instances of Magics.

        Take one or more classes or instances of classes that subclass the main 
        `core.Magic` class, and register them with IPython to use the magic
        functions they provide.  The registration process will then ensure that
        any methods that have decorated to provide line and/or cell magics will
        be recognized with the `%x`/`%%x` syntax as a line/cell magic
        respectively.

        If classes are given, they will be instantiated with the default
        constructor.  If your classes need a custom constructor, you should
        instanitate them first and pass the instance.

        The provided arguments can be an arbitrary mix of classes and instances.
