+/**
+    @file
+    @ingroup Command FunctorExecutor
+    @brief Typedefs and definitions of ExecutorPtr, ExecutorStaticPtr, and ExecutorMemberPtr
+
+    Instances of orxonox::Executor are usually managed by an orxonox::SharedPtr. This ensures
+    that Executors will be destroyed after usage. To make things easier, there's a typedef
+    that defines ExecutorPtr as SharedPtr<Executor>.
+
+    Because there's not only orxonox::Executor, but also orxonox::ExecutorStatic, and
+    orxonox::ExecutorMember, the shared pointers need to store them all and also reflect
+    their hierarchy - ExecutorStatic and ExecutorMember should not be mixed, but both can
+    be converted to Executor. This is achieved by using orxonox::SharedChildPtr.
+
+    Because it's not possible to use a typedef for a template, we have to define the
+    helper class ExecutorMemberPtr<T> that makes it easier to use ExecutorMember.
