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 in mfem::VectorRestrictedCoefficient, mfem::GradientGridFunctionCoefficient, and mfem::VectorGridFunctionCoefficient.

inline 
Returns dimension of the vector.

virtual 
Fill the QuadratureFunction qf by evaluating the coefficient at the quadrature points.
The vdim of the VectorCoefficient should be equal to the vdim of the QuadratureFunction.
