The current script covers all 1DC tutorials.

…. As the necessary separation angle depends on the rotation angle but also on the rectangle extension (overlaps may easily occur) the computation is not so easy: I implemented a rough (slightly overestimating) algorithm which chooses the maximum opening angle between the corners of the rectangle with respect to the pointing position. Extended implementation of _reflected_regions() method to allow the placement of rectangular off regions, which is essentially finally placing a rectangle instead of a circle.

…ontaining the pointing (should be equal, but has greater flexibility for different (filled) region types)

…et_state and set_state methods.
