Feature: Gauss-Radau quadratures

Adds the Gauss-Radau quadrature rules (quadrature rules that include either the left or right endpoint of the interval) Also some minor refactoring of the maxima scripts that generate the quadrature rules. The refactoring leaves the output of the scripts, i.e., gauss_imp.hh, jacobi_1_0_imp.hh, jacobi_2_0_imp.hh, gausslobatto_imp.hh unchanged.

unmarked as a Work In Progress

I guess the writequad_old.mac is a mistake?!

Is there a reason that the max-order is less than for the other rules?

highest_order was 61 for the Gauss-Jacobi type rules and 31 for the Gauss-Lobatto rules before. I don't know what the reason for that was either. I just decided to pick the same order for Gauss-Radau rules as for the Gauss-Lobatto rules. Because the Radau rules are defined for even orders only, the highest_order ended up as 30.

I think it is always easier to increase the order later if needed, than decrease it and risk breaking compatibility.

As far as I am concerned, this thing is ready to be merged. If it is even wanted / needed.

Thanks, I'll have a look tomorrow.

Could you please also add a changelog entry.

Besides these documentation remarks everything looks good. Thanks!
