Abstractclassmethod

Implementation of a new abstractclassmethod property.

abstractclassmethod

Bases: classmethod

Python 2.7 does not include built in @abstractclassmethod so we create our own class that extends @classmethod and then attaches a __isabstractmethod variable to the callable function. See ref: https://stackoverflow.com/a/11218474
