cache so I don't need the internets?

I have run the same set of kplr commands many time, but when I turn off the internet I get:

Traceback (most recent call last):

ps. if it downloads every time, perhaps it should cache and check the cache first?

pps. We just sort-of decided on a use_cache = True style modification.
