fix of pss ring with points_inside_touching_sides 

Change of function point_inside_touching_sides (renamed
to points_inside_touching_sides) in order to process correctly
inputs like br80.cin:
s       10      120     60      20
s       60      40      70      60
s       30      110     100     40

(segments AB, CD, EF, respectively)

The incircle predicate (CD, B, F, EF) returns 0.
