[feature][MassLumpingOp] Added derivation of Galerkin with mass lumping.
This is a test implementation to see what a good approach would be. The implementation is straight forward on the expense of an extra grid traversal. This could be prevented with some modification to GalerkinOp.
TODOS:
-
Naming of the Scheme, class, etc. -
Better integration with GalerkinOp -
Extension to multiple Integrands models (optional)
