TODO FIRST !

A user element is needed in order to use this scene.
To do that, simply select "Add new element..." in
the top right list, a popup will ask you some info,
press continue, then in the top left menu select "load"
and choose the "object_distance.aml" file included in
the zip file. At this point you have the needed user
element, select "Main program" in the top right menu
and you are up and running...
