Estimates the normals and curvature for a sparse 3D point cloud, by using the n nearest neighbours to approximate a plane at each point.
-Able to process point clouds of over 1 million points in under 60 seconds.
-Robust to flipped normal direction
-Uses a nearest neighbour search (as opposed to a range search) to minimize parameter tuning and allow handling of point clouds with highly non-uniform density.

Zip appeared empty, re-uploaded to fix
1.3.0.0

Not using eig gives inaccurate results under some conditions, reverting to previous version till I can track down and fix the issue
1.2.0.0

Abandoned Matlabs eig function in favour of calculating eigenvalues and vectors analytically. Allowed for vectorization of the code and a speed improvement of at least 2x.
Also changed default value of dirLargest to false
