QuadratureFunctions

The QuadratureFunctions syntax is used to declare MFEM coefficients that hold precomputed values of a source coefficient at the quadrature points of an MFEM QuadratureSpace, backed by an MFEM QuadratureFunction. The declared coefficient may be used in place of the source coefficient wherever a scalar coefficient name is accepted, avoiding repeated evaluation of expensive source coefficients, and is re-projected from the source upon a schedule set by the user.
