beginning editing of spatial solvers theory. I've just changed the first two sections so far. What to make many small increments as I suspect I'll want some undos.
more changes; part way through and need to pull.
I think I've updates these in some useful way?

cleanup of intro
added a paragraph about the methods in general.

cleanup through ahotn general; got the section linking stuff to work.
finished cleanup of the theory manual. It's not very good, but it's not terrible. I'm going to send it to Sebastian for input.
fixed a few typos
Updated spatial solver api
Merge branch 'tmpdev' of https://github.com/rachelslaybaugh/pyne into transport-josh-dev
changed tabs to spaces.
started cleaning up solve.f90 for tabs and spaces.
making progress on cleaning up api; need to fix convergence descriptions and then key entries will be finished. Haven't gotten farther than that yet.
converged tabs to spaces in inner; deleted a bunch of extra stuff in main; added author tribute in main.
finished with input key-value items; changed heading in theory manual so it oculd be referenced.
