- Added a missing operator*() for diagonal by diagonal matrix multiplication. · e9df8898

   Without it you would get an error about multiplication being ambiguous

 - Added an overload to catch expressions of the form diag_matrix*regular_matrix*diag_matrix
   and turn them into a form which is slightly more numerically stable in some cases.
