Undocumented `changes` endpoint in Simperium HTTP doc?

[gedex]

In bulk_post of Bucket class, you're making request to changes endpoint, but I couldn't find it on Simperium HTTP doc. I'm writing a client with a method to send buffered entities at once, pretty much like bulk_post. Would be good to have reference for that endpoint (like available query params and expected responses).

This is merely a question not an issue with this Python wrapper.
