Detailed Description

template<typename T, std::size_t NDIM, std::size_t MDIM>
class madness::CompositeFunctorInterface< T, NDIM, MDIM >

CompositeFunctorInterface implements a wrapper of holding several functions and functors.

Use this to "connect" several functions and/or functors and to return their coefficients e.g. connect f1 and f2 with an addition, you can request the coefficients of any node and they will be computed on the fly and returned. Mainly useful to connect a functor with a function, if the functor is too large to be represented in MRA (e.g. 1/r12)

as of now, the operation connecting the functions/functors is simply addition. need to implement expression templates, if I only knew what that was...
