+The regular triangulation of a set of weighted point does not
+necessarily
+have one vertex for each of the input points. Some of the input
+weigthed points have no cell in the dual power diagrams
+and therefore do not correspond to a vertex of the regular
+triangulation.
+Those weighted point are said to be {\it hidden} points.
+A  point which is hidden at a given time may appear later as a vertex of
+the regular triangulation upon removal on some other weighted point.
+Therefore, hidden points have to be stored somewhere.
+A hidden point can appear as vertex of the triangulation
+only when the
+two dimensional face where its point component is located
+(the face which hides it)
+is removed. Therefore we decided to store each hidden point
+in the face which  hides it and the nested face type of a 
+regular triangulation is assumed to include a list of hidden 
+weighted points. This list of weighted point is in fact included
+in the base face of a regular triangulation.
