[Numpy-discussion] Proposal: scipy.spatial

[David Bolme]

I also like the idea of a scipy.spatial library.  For the research I  
do in machine learning and computer vision we are often interested in  
specifying different distance measures.  It would be nice to have a  
way to specify the distance measure.  I would like to see a standard  
set included: City Block, Euclidean, Correlation, etc as well as a  
capability for a user defined distance or similarity function.
