Black box

Black box is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Implement a version of the Black Box game beginners configuration: 4 Atoms in an 8 x 8 grid.

Determine where the hidden atoms are in the box, by observing how the light beams fired into the box react when leaving it.
Possible results:
'H': the beam hit an atom and stopped
'R': Either the beam was reflected back the way it came or there was a ball just to one side of its entry point
'Numbers': indicate that the beam entered one of those squares and emerged from the other

Extra credit (Different game types):
-More or less atoms (maybe random)
-Different grid sizes
