PITTNullCode lacks documentation
Issue #1440
new
currently the PITTNull code has not (Cactus) documentation and only refers toarXiv:1011.4223 in the README file of eg NullEvolve. I would like to have a section "Physical System" that gives definitions for the evolved variables, ideally also a section on the numerical implementation and in a perfect world and example on how to use it.
The first two might conceivably be just sections from the relevant papers while the last could be from Yosef's CCE tutorial [http://ccrg.rit.edu/~yosef/cce.html].
