Remarks

Class to define an indexed 2D mesh. Each cell of this type of mesh is a polygon with any number of nodes. Each polygon cell is defined by a list of indices in an array of nodes.

The nodes coordinates are defined by 2 (or 3) arrays x_nod, y_nod (and z_nod) of num_nodes floats. The cells are defined by the array cell_type (size num_cells) and cell_index. cell_type[n] defines the number of nodes in the n-th cells: if cell_type[i] = 3, the i-th cell is a triangle, if cell_type[i] = 4, it is a quadrangle... cell_index is an array of S integers, where S = cell_type[0] + cell_type[1] + ... + cell_type[num_nodes - 1]. cell_index contains the num_cells lists of node indices which define each cell topology.

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