    """A decorator indicating abstract methods.
    Requires that the metaclass is ABCMeta or derived from it.  A
    class that has a metaclass derived from ABCMeta cannot be
    instantiated unless all of its abstract methods are overridden.
    The abstract methods can be called using any of the normal
    \super\ call mechanisms.
    Usage:
    class C:
    __metaclass__ = ABCMeta
    @abstractmethod
    def my_abstract_method(self, ...):
