0D Meshers (Points)
Introduction
In most cases, it is not necessary to mesh 0D entites (points). Such a mesh point is automatically generated when a line which includes it on one extremity is meshed. If the point must be meshed on its own, for example when the point is the reference point of a string, it is done with the command:
point.mesh()
0D Mesh
Manually
To create a 0D mesh element on a mesh point:
mesh.define(no, CELL_POINT, grp, no1)
where
Automatically: CellPointMesher
CellPointMesher is a mesher which generates objects of type CELL_POINT in the topology, based on meshed geometric entities (which contains some MeshedPoints).
Le père de la maille est mis sur l'entité passée au CellPointMesher (pour le FieldApplicator). 
Example:
Generation of a CELL_POINT on a ''Group' of mesh points, which come from a Bacon import for example.
mesher = CellPointMesher(groupset(no)) mesher.execute()

not used, in practice the mesh element is represented by the point itself and has the same number (
