Implement integral2/sum2 for ultraSEM.Sol #31

Closed danfortunato closed 4 years ago

danfortunato commented 4 years ago

This PR implements integral2 and sum2 for ultraSEM.Sol. On each patch, bivariate Clenshaw-Curtis quadrature is used at N+1 x N+1 points, where N is the degree of polynomial approximation on that patch.
