Enh/add caching

[jdkent]

• I've considered some of the weird relationships between tables: annotations and studyset_studies to make sure the caches are invalidated when there are changes to other tables
• I've considered when authorization is passed with the headers (like when looking at the studies endpoint when you have studies that you own that would show up during a search)
• I have considered the nesting of objects so when you update a coordinate, you should invalidate the cache of analyses, studies, etc.
• there are likely weird scenarios afoot, maybe if a point is deleted and an analysis is viewed without nesting, the id of the point may still show up?

be ready for weird errors!
