Detailed Description

template<class PERM, class MATRIX>
class permlib::partition::MatrixRefinement1< PERM, MATRIX >

concrete $\mathcal P$-refinement for symmetric matrix automorphisms

exploits that if $\alpha^g=\beta$ then the rows $\alpha,\beta$ must have the same diagonal elements for an automorphism $g$
