Remarks

Class to define an indexed 2D mesh made up of triangles cells. This mesh is defined by a list of triangles. Each triangles is defined by 3 indices of nodes.

The nodes coordinates are defined by 2 (or 3) arrays x_nod, y_nod, (and z_nod) of num_nodes floats. The triangles are defined by the array triangle_index of num_triangles*3 integers. triangle_index[(n*3)+p] is the p-th node index of the n-th triangle of the mesh (0 <= p <= 3).

Each edge of a triangle may have 2 references in the mesh, that is, one edge is common to 2 triangles. The edges which are referred to once in the mesh define the limits of the mesh.

The geometry of this mesh can be defined also from a points field. In this case the Voronoi method is used to build the triangle mesh.

The values on the mesh nodes are defined by the PbMesh.addValuesSet(set_index,val) method, where val argument is an array of num_nodes floats.
