Description

I've pieced together a working boilerplate for changefeed interaction demonstration with a Redux store.

boilerplate documentation will be included over time - however, it's fairly simple to follow how Redux is alternatively triggered by RethinkDB changefeeds as opposed to immediately triggering redux action creators. User actions in this case trigger a RethinkDB query which in-turn send changefeeds to trigger redux action creators.

Thank you. I've merged this to master. It might take some time to get on the website.
