new attempt
active plan class
active plan class
distance function correction
active plan 2 constructor
save
compute direction plan
remove duplicate edge in intersection
Filtering invalid Event implemented
chain creation without orientation correction
chain construction: now th chain should be sorted around the intersection
first try to code the intra chain algorithm
intra chain algorithm corrected
inter chain algorithme first try (need to debug it)
inter chain algorithm updated
inter chain algorithm updated and debugged + active plan updated
strange case
correction when chain = 1 after inter chain
without the print
additional iteration to fill the hole
