32    @brief Typedefs and definitions of FunctorPtr, FunctorMemberPtr, FunctorStaticPtr, and FunctorPointerPtr
33
34    Instances of orxonox::Functor are usually managed by an std::shared_ptr. This ensures
35    that Functors will be destroyed after usage. To make things easier, there's a typedef
36    that defines FunctorPtr as std::shared_ptr<Functor>.
37
38    Because there's not only orxonox::Functor, but also orxonox::FunctorStatic, and
39    orxonox::FunctorMember, the shared pointers need to store them all and also reflect
40    their hierarchy - FunctorStatic and FunctorMember should not be mixed, but both can
41    be converted to Functor. This is achieved by using orxonox::SharedChildPtr.
42
43    Because it's not possible to use a typedef for a template, we have to define the
44    helper class FunctorMemberPtr<T> that makes it easier to use FunctorMember. The
45    same is also done for FunctorPointerPtr<T>, which can be converted to both,
46    FunctorMemberPtr<T> as well as FunctorPtr.
