virtual 
Evaluate the vector coefficient in the element described by T at all points of ir, storing the result in M.
The dimensions of M are GetVDim() by ir.GetNPoints() and they must be set by the implementation of this method.
The general implementation provided by the base class (using the Eval method for one IntegrationPoint at a time) can be overloaded for more efficient implementation.
Reimplemented from mfem::VectorCoefficient.
