Docs overhaul 2: First Blood

* moves some theory stuff to a new theory chapter!
* clean up references (remove the parens)
* clean up documentation by focusing on sentences that are too dense
  "new idea"-wise
* removed a bunch of JSON because it's not very helpful to know and
  it's impossible to update
* broke things into sections so they're faster to find via tables of
  contents
* cleaned up the quickstart sample program
* nixed the big JSON blob thing
* moved documentation to docstrings in the code
* moved MLT to queries docs
