...atrix

The second commit should be treated as a suggestion. I am not entirely sure whether these changes break any existing code, although I think they should be safe enough.

This fixes a conflict with "gap -O", as the "VERSION" variable
is deprecated in GAP these days.

The following example indicates that the LIMAT/COLEM methods might be slowing down the computations:

LoadPackage( "GradedRingForHomalg" );
S := GradedRing( HomalgFieldOfRationalsInDefaultCAS( ) * "x,y,z" );
LoadPackage( "GradedModules" );
I := GradedLeftSubmodule( "x", S ) * MaximalGradedLeftIdeal( S )
     + GradedLeftSubmodule( "y^3", S );
M := FactorObject( I );
homalgIOMode( "D" );
FilteredByPurity( M );

This seems to be a shared issue between Matrices and Gauss. Matrices' Determinant method does not check whether its argument is a dense matrix. Gauss does not implement Determinant at all.

gap> m := HomalgMatrix( [[1]], HomalgFieldOfRationals() );
gap> Determinant( m );
Error, Record: '.matrix' must have an assigned value in
return Determinant( Eval( C )!.matrix ); called from
DeterminantMat( C )
brk> IsIdenticalObj(C,m);

rec( attributes := rec( ), components := rec( entries := [ [ 1 ] ], indices := [ [ 1 ] ], ncols := 1, nrows := 1, ring := Rationals ), object := <a 1 x 1 sparse matrix over Rationals>, properties := rec( ) )
