Description: Function to calculate the principal curvatures on a triangular mesh. Approximations of curvature are based on local (N=1) neighborhood elements and vertices.
Note: Directions of curvatures aren t calculated appropriately. Will post an updated version once this is implemented.
Note that calculations at vertices with few adjacent triangles, and hence few adjacent vertices, are expanded to a greater neighborhood.

Description: [K,H,P1,P2] = surfature(X,Y,Z) returns the gaussian curvature of a surface (K), mean curvature (H), and principal curvatures (P1,P2). The inputs (X,Y,Z) are 2D arrays corresponding to the surface being analyzed.
Example
[X,Y,Z] = peaks
[K,H,P1,P2] = surfature(X,Y,Z)
surf(X,Y,Z,H, facecolor , interp )
set(gca, clim ,[-1,1])
