Traits for image functors.

Image functors are functors designed for images only. I.e. they concern things less trivial that simple intensity transformation. For example, they could use the value of their neighbors. Therefore, the first difference between a numerical functor and an image functor is that an image functor takes image iterators as an input. Still – image iterators are something more general and independant of template expressions, which is why they are separated here and need these traits to embed them in template expressions. Actually, again, we need these traits only to get the type of the returned value. In other words, to compensate for the lack of typeof...
