* 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.
