Management, updating and computation of per-vertex and per-face normals.
This class is used to compute or update the normals that can be stored in the vertex or face component of a mesh.

Curvature meseaure as described in the paper: Robust principal curvatures on Multiple Scales, Yong-Liang Yang, Yu-Kun Lai, Shi-Min Hu Helmut Pottmann SGP 2004 If pointVSfaceInt==true the covariance is computed by montecarlo sampling on the mesh (faster) If pointVSfaceInt==false the covariance is computed by (analytic)integration over the surface (slower)
