[pymvpa] SOM with a hexagone lattice

[Bas van den Broek]

Hi all,

I'd love to use PyMVPA for making a SOM with a hexagone lattice. Is this 
perhaps something that could be implemented in a future version?

(I'm not sure, but I think only the def _train method would need to 
change a bit, unfolding the kernel to two more units.)

Thanks in advance!
