Update eigenvalues() and operatorNorm() methods in MatrixBase. * use SelfAdjointView instead of Eigen2's SelfAdjoint flag. * add tests and documentation. * allow eigenvalues() for non-selfadjoint matrices. * they no longer depend only on SelfAdjointEigenSolver, so move them to a separate file 2010-05-24 17:43:50 +01:00			`MatrixXd ones = MatrixXd::Ones(3,3);`
