MFEMNodalProjector

Auxiliary class for extracting nodal positions/interpolation points from MFEM FESpaces, and for setting DoFs on MFEM GridFunctions via projection given a vector of values evaluated at these nodes.

End users should not need to interact with MFEMNodalProjector directly. MFEMNodalProjector is used by MFEM transfers that set values of an MFEMGridFunction, such as MultiAppMFEMShapeEvaluationTransfer.
