clustering

[Francesco Potortì]

I finally got down to completely rewriting the clustering functions
pdist.m and linkage.m in the statistics package.  They should be now
completely compatible with Matlab's.  If you want to use them now, they
are compatible with Octave 3.0.  You can download them from
