Detailed Description

template<typename BinaryFunctionT>
class lsst::afw::math::details::FunctionWrapper< BinaryFunctionT >

Wrap an integrand in a call to a 1D integrator: romberg()

When romberg2D() is called, it wraps the integrand it was given in a FunctionWrapper functor. This wrapper calls romberg() on the integrand to get a 1D (along the x-coord, for constant y) result . romberg2D() then calls romberg() with the FunctionWrapper functor as an integrand.
