        /** This class stores information about the simplification process, giving for each step the four triangles that compose the two leaves that will be collapsed
        and the two triangles of the new leaf. 
        It also offers a method to generate a tree simplification sequence format file.
        \n
        This file begins with a line stating the name of the mesh file it refers to.

This file stores the leaves geometry and at the end of the file one line for each leaf collapse operation. \n

v …\n
f       // faces sequence (two faces compose one leaf) including new faces\n
f       // added due to the simplification process\n
f …\n
end\n
// one collapse record per line\n

Those records gives the following information:\n

        -# The four triangles that compose the two leaves that will be collapsed.\n
        -# & as a separator.\n
        -# The two triangles for the new leaf.\n
