# Important: If we do a division of edges, the points are numered in
# this manner:
# We get a edge numered as first point with number 0 and last point
# with number 1. when we do a division, each division are numered from
# point 0 to ndivision, but the point number 1 is still the number one
# so for example, in a edge [0,1] with 5 divions the number are
# [0,2,3,4,1].
