60a9dbe]||{{{Added boolean keyword 'transposition' to mark computation of
a matrix U such that U*A=A.wpf(). This is to check correctness of a
computation. If B = copy(A) and after A.weak_popov_form()
U.is_invertible()==True and A.is_weak_popov()==True then A is in weak
popov form and is unimodular equivalent to B its origin.}}}||
