did I fix it?
Fixed bug from issue #412. The right eigenvectors were not being computed when the kwarg was specified. I fixed this, and also added the kwarg for normalizing the eigenvectors. Finally I added tests for comparing thetwo methods for computing right and left eigenvectors as well as a test for the normalization.
got the tests working. I had inadvertantly broken the get_eigenvectors method. I think it's all working now.
fixed docstrings to work with sphinx for the eigenvector stuff
