Updated v_Integral method so that default weights in the collapsed coordinate direction are the given weights scaled by the appropriate Jacobian. This implies that the provided weights are of for a standard Legendre inner product unless otherwise specfiied by another switch case.

clamp_low and clamp_up modified in order for the CFS to get a proper interpolation for the energy. Commented out Checkbndmeshes2D and put bool check = true. Indentation fixed.
