Simon Giraudot e8dd34cb21 Implemented the efficient computation of the second centroid. 
The hierarchical clustering algorithm gets about 15% faster
(on test Eglise Fontaine, from 91s to 76s).

Simon Giraudot ee1e7ee714 Added the alternative implementation of hierarchical clustering using 
the Eigen library.

For now, both implementations are available (switchable with a

Pierre Alliez 00fad8756a Add comments in hierarchical clustering and fix indentations 2015-10-07 16:00:50 +02:00
Simon Giraudot b87d1bbc3e Very first version of the hierarchical clustering added (work in 
progress).

It contains somes functions that may be more relevant in some other
package :
* 2 functions to compute the covariance matrix of a 3D point set
* 2 functions to split a point set according to a plane

Also the function of the actual hierachical clustering algorithm.
