What is more, the current implementation of the move_point of 
Regular_triangulation_3 is just an erase followed by an insert of the new 
point. That corrupts all cells attributes of the modified zone. And the C3t3 
object uses cell attributes to store its data structure. It means that a 
move_point corrupts the C3t3 in a neighborhood of the moved point.
