Not to sound like a broken record, but have the docs covering the unit
refactor, SPH smoothing, and all of the other new things in unit refactor
been written?  Or are you just talking here about moving the yt-docs
repository (which only covers yt 2.x) into the yt-3.0 branch of the yt
repository?  I'm excited to use the new yt, but I just want to make sure I
know how and it is clear how it all works under the hood.
