Local curvauture distributions with signs for 1409 atoms

Instead of the absolute values of local cuvatures, signs have been add in. The sign of a curvature is positive if the surface bends toward the normal vector. The directions of normal vectors of the parabolic fitting are turned in pointing toward the system center of mass so that most of the curvatures are positive.

Average curvature = (small+large)/2
Gaussian curvature = small*large

All of the calculations are taken by method 2 with cutoff=3.8.
