class madness::ElementaryInterface< T, NDIM >
ElementaryInterface (formerly FunctorInterfaceWrapper) interfaces a c-function. 
hard-code your favorite function and interface it with this; Does only provide function values, no MRA coefficients. Care must be taken if the function we refer to is a singular function, and a on-demand function at the same time, since direct computation of coefficients via mraimpl::project might suffer from inaccurate quadrature.
