This class converts a map to an STL style (unary) functor. That is it provides an operator() to read its values.
For the sake of convenience it also works as a usual readable map, i.e. operator[] and the Key and Value typedefs also exist.
The simplest way of using this map is through the mapToFunctor() function.
