+    @brief Definition of the Tickable interface.
+
+    The Tickable interface provides a tick(dt) function, that gets called every frame.
+    float dt is the time since the last frame in seconds.
+
+    Attention:
+    Classes derived from a Tickable that want to have a tick(dt) function on their part, MUST call the
+    parent::tick(dt) function explicitly in their implementation of tick(dt) because it's a virtual function.
