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

This defines a read-only property; you can also define a read-write
    abstract property using the 'long' form of property declaration:

class C:
            __metaclass__ = ABCMeta
            def getx(self): ...
            def setx(self, value): ...
            x = abstractproperty(getx, setx)

Use this metaclass to create an ABC.  An ABC can be subclassed
    directly, and then acts as a mix-in class.  You can also register
    unrelated concrete classes (even built-in classes) and unrelated
    ABCs as 'virtual subclasses' -- these and their descendants will
    be considered subclasses of the registering ABC by the built-in
    issubclass() function, but the registering ABC won't show up in
    their MRO (Method Resolution Order) nor will method
    implementations defined by the registering ABC be callable (not
    even via super()).
