  Changed paths:

  Log Message:
  -----------
  return const& where  possible (but not for expressions)

Note: This fixes a bug triggered by
test_CMSSM_effective_couplings.cpp:

When model.get_UM() returns an Eigen::Matrix<>, then the matrix U
defined by

   const auto U = (model.get_UM()).conjugate();

is wrong.  However, when model.get_UM() returns a const
Eigen::Matrix<>&, then the U defined above is correct.
