You are right, Julien, but the 'anima' function will
be called in C++ code;
The 'setCallback' is a method of the Animation class.
My doubt is how to declare the method 'setCallback' in
tolua, and how to store in the C++ code the reference
to the Lua funcion and how to call it later, passing
the 'runner' object.
