winged-edge mesh subdivision (meshlab shading)

For an upcoming project I need to build a vertex traversal graph for huge 3D meshes (few million triangles+), so that I can efficiently navigate from a given vertex to its various neighbours and so forth... So I've implemented the Winged-Edge structure on top the existing TriangleMesh class in toxiclibs and then quickly implemented some basic subdivision strategy too (mainly to test the system for correctness and performance).
