def get_all_subclasses(cls):
    '''
    Recursively search and find all subclasses of a given class

:arg cls: A python class
    :rtype: set
    :returns: The set of python classes which are the subclasses of `cls`.

In python, you can use a class's :py:meth:`__subclasses__` method to determine what subclasses
    of a class exist.  However, `__subclasses__` only goes one level deep.  This function searches
    each child class's `__subclasses__` method to find all of the descendent classes.  It then
    returns an iterable of the descendent classes.
    '''
    # Retrieve direct subclasses
    subclasses = set(cls.__subclasses__())
    to_visit = list(subclasses)
    # Then visit all subclasses
    while to_visit:
        for sc in to_visit:
            # The current class is now visited, so remove it from list
            to_visit.remove(sc)
            # Appending all subclasses to visit and keep a reference of available class

                if ssc not in subclasses:
