Detailed Description

Simple little class to hold a generator (uninitialised) and the necessary args/kwargs to
initialise it. This lets us reuse a generator by setting it up again fresh. This is not
optimal for expensive calculations, but it is nice for making large sequences of
Job input arguments on the fly.

Constructor & Destructor Documentation

__init__()

__init__	(		self,
			generator_function,
		*	args,
		**	kwargs )

Parameters:
    generator_function (py:function): A function (callable) that contains a ``yield`` statement. This generator
        should *not* be initialised i.e. you haven't called it with ``generator_function(*args, **kwargs)``
        yet. That will happen when accessing the `ArgumentsGenerator.generator` property.
    args (tuple): The positional arguments you want to send into the initialisation of the generator.
    kwargs (dict): The keyword arguments you want to send into the initialisation of the generator.

Returns:

    to have ``next``/``send`` called on it.
