Detailed Description

template<class F1, class F2>
struct vigra_ext::NestFunctor< F1, F2 >

functor to combine two functors: result = f1( f2(v) )

The functors are copied, so there is no way to get their internal state after they have been applied.

This is quite useful for multithreaded processing.
