    @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.
