/** @brief Scene is a subclass of Node that is used only as an abstract concept.

Scene an Node are almost identical with the difference that Scene has it's
anchor point (by default) at the center of the screen.

For the moment Scene has no other logic than that, but in future releases it might have
additional logic.

It is a good practice to use and Scene as the parent of all your nodes.
