add() returns the value being added if subject is not nil
del() returns the value removed, if found in the table (implies subject is not nil)
atan2() returns are [0,1[ instead of ]-π,π]
atan2() returns are offset by -1/4 of the circle

Also, this PR makes Pico Tennis not crash anymore (behavior is still weird)
