This class implements the Marching Cubes algorithm.
The implementation is enough generic: this class works only on one volume cell for each call to ProcessCell. Using the field value at the cell corners, it adds to the mesh the triangles set approximating the surface that cross that cell. The ambiguities are resolved using an enhanced topologically controlled lookup table.
