Normalizing for Anisotropy in Triangle Models

--in <input mesh>

This string is the name of the file containing the triangulated model. It is assumed that the file is in the PLY format and the file-name ends with a ".ply" extension.

--out <output triangle mesh>

This string is the name of the file to which the triangle mesh will be written. The output file will be in the PLY format and it the file-name should end with a ".ply" extension.
Note that this code can handle an arbitrary polygonized mesh, but the output file will always be triangulated. The triangulation is obtained by adding a new vertex at the center of a non-triangle face and decomposing the fact into triangles that maintain the same orientation.
While the code will modify the anisotropic parameters of the model, the overall scale, translation, and rotation remain unchanged.

[--iter <number of iterations>]

This argument specifies the number of anisotropy normalizations that are to be preformed. If no argument is specified, a default value of five iterations is used.
