This PR is supposed to replace #251.
It is a substantial refactoring of Isaac's original script, but accomplishes the same thing: plots of the cloud regimes and maps of frequency of occurrence of cloud regimes. This works with ISCCP, MODIS, and MISR cloud regimes. There are a number of options available, and they should be set using the argument dictionary approach in the configuration YAML file.
I've done testing for ISCCP histograms, but haven't repeated for MODIS and MISR so far.
There are quite a few helper functions included. I have tried to organize them into the categories:

In particular, the land/ocean masking and the regridding should probably be removed for more generalized versions of those functions that can be used across ADF scripts.
