introduced new classes, Face, Vertex and ObjReader which will fabricate a shape for jrtr engine from given meshgrid stored within an external read .obj file. Goal: Try to handle as many format veriants for .obj files as possible, or at least those which im dealing with such as the teapot meshgrid or the data provided by the lab in geneva. after having read the mesh into java, create faces (of the triangles) and assign the corresponding values - see formal explenation written in thesis. after having built up this vertexData objec, iterate over each face and compute the corresponding approximate tangents for each vertex by weighting summation over each projected direction vector - derived by the the vertices for each face (using gram-Schmidt orthogonalization).
