* document Gowdy-wave model (this was missing from the thorn guide)

* add a new feature that any vacuum non-cosmological-constant solution
  can be Lorentz-boosted by any 3-velocity
  (previously, Kerr/Kerr-Schild had the ability to do a z-axis boost,
  but the new code works for most of the models, and can boost in any direction)
* general cleanup of most of the individual models to systematize
  comment conventions for subroutine arguments: input arguments,
  output arguments, static local variables, local variables, parameters
* cleanup comments in various places to describe conformal factor
  being passed to/from individual models (this was in the code before,
  but not consistently documented)
* various other cleanups in documentation

There should be no change in the operation of any of the existing models.
