PCVM pattern

Getting up to speed in the React world, there's a pattern which started to emerge in previous worlds, but seems to be getting clearer. I haven't seen a name for it yet, so I'll call it the PCVM pattern.

Combine that with a module to tie asynchronous state updates (say from a database) with the store (Redux-thunk), and patterns for JWT authentication, and you've gone a long way toward a fullsome front-end stack.
