  Log:
  Normal calculation for junction points with degree 3 or higher.
  
  These normals are calculated as the normalized resultant of all the incoming segments
  to the junctions of degree 3 and higher. A button has been added to flip normals in
  case they're in the wrong direction.
  
  There exist some obvious counter-examples to this approach, but we can either:
  1.- Ignore them for the moment and focus on the cases when this works.
  2.- Provide a rotation control to modify precalculated normals.
  3.- Improve the normal calculation scheme to account for coherence of orientation with
  respect to the neighbors. This would be the equivalent of a median (Laplacian?) filter
  in the normals of the neighborhood of each junction point.
  
  Anyway, so far we're going for the first solution, a.k.a. The Ostrich Approach (tm).
  
  Next:
  - Manual identification of faces. The user succesively marks the segments that
  compound each face in counter-clowkwise order. Existing faces should be viewable,
  selectable and erasable with the usual one-button approach.
