Schur decomposition in eigen? #35

For non symmetric systems, a Schur decomposition instead of an eigenvalue decomposition is used internally. This is a preparation for the non-symmetric case.

So Eigen has a Schur decomposition, but the sorting of eigenvalues gets more complicated for schur decomposition, so the rodering of schur vectors would have to be implemented which is really not easy.
