Nathan Goldbaum:

So for some reason my test data directory has an "orion2.ini" file in it. This means that any data directories I try to load are getting recognized incorrectly as orion2 datasets.

I think the orion2 frontend should be smarter about this, maybe by checking if other files exist before returning from `_is_valid`.

@atmyers do you have thoughts about this?
