Detailed Description

this object extracts the dofs for each element in a FiniteElementSpace as a 2D array such that element_dofs_(e, i) will be the ith dof of element e.

Note: due to an internal inconsistency between mfem::FiniteElementSpace and mfem::FaceRestriction, we choose to use the Restriction operator as the "source of truth", since we are also using its convention for quadrature point numbering.
