Anders is one step ahead of us - he added the class Coefficient which has:
virtual void eval(double* values, const double* x) const;
virtual void eval(double* values, const Data& data) const;
virtual void restrict(double* w,
const FiniteElement& element,
const Cell& dolfin_cell,
const ufc::cell& ufc_cell,
int local_facet) const;
virtual void evaluate(double* values,
const double* coordinates,
const ufc::cell& cell) const;
