code: def alias(name, class_object):

docs: Create an alias of a class object
  
      The objective of this method is to have
      an alias that is Registered. i.e If we have
  
          class_b = class_a
  
      Makes `class_b` an alias of `class_a`, but if
      `class_a` is registered by its metaclass,
      `class_b` is not. The solution
  
          alias('class_b', class_a)
  
      is equivalent to:
  
          class_b = class_a
          Register['class_b'] = class_a
