Since we renamed subregions_dict to regions_dict, it would be a good idea to change all instances of "subregions = functions.get_from_yaml('regions_dict')" to "regions = functions.get_from_yaml('regions_dict')", since it is probably more clear that way. We should also change wherever the subregions variable is called to regions.
The reason that it is the way it is is that regions_dict does contain subregion information, but the way it is is probably unnecessarily confusing.
