Detailed Description

template<std::size_t NDIM>
class madness::DomainMaskSDFFunctor< NDIM >

Framework for combining a signed distance function (sdf) with a domain mask to produce MADNESS functions.

This interface provides functor functionality to produce MADNESS functions for

the domain mask (given the sdf)
the derivative of the domain mask
the surface (given the sdf)
the normal derivative of the surface layer

The functor defaults to the domain mask; however, member functions can toggle between the other options.
