ROCK2 Reorganization #432
Description
As mentioned here: #374 (comment) , the ROCK2 code is organized like the origional Fortran code but this is not very easy to follow. We should set it up more like the paper, so there should be arrays of mu and nu coefficients, and mus[j] should give the array of mu coefficients so that mus[j][i] directly matches the paper. Also, the eigenvalue calculation is a little obfuscated so that could be cleared up.
