Please review my changes to models and my two new tests. Am I creating relationships in the best way possible? How could I create time exceptions (i.e. on  dates A and B the resource closes early)?
I think the third enum would actually be `FOOD_CUPBOARD`. (I don't think that one of their resources is a "list of food cupboards" - I can confirm this with them though, if you'd like.)
