Running your own scheduler

I am working on the documentation to be able to run your own call scheduler.  I've been busier than I expected since getting back from the conference so it's been hard to make happen.  I'm hoping to get it done over the next few weeks.

In other news, I'm making progress on solving the problems that will enable removal of the Caller Pool system, and that will make scheduled calls truly portable, allowing them to be migrated in a trustless manner into newer versions of the service.  I'm still working out some of the math and game theory so stay tuned for a write-up on how it's being solved.
