Multiple RHSs on solvers in Fortran. ~2x speed up on matlab implementation for a single RHS. for multiple RHS there are still some problems.

Someone with some knowledge of how fortran works should look at this code.

Added a setup.py script that complies things. f2py should work on most computers, because it is included in the numpy distribution.
