[SciPy-dev] Sorting speed

[Travis Oliphant]

I've checked in sorting improvements to scipy_core SVN.

I've also added a benchmarks directory for storing little benchmark 
programs.  The attached program is already there.

It's output for me is:

1-D length = 10000
Numarray:  [0.26125383377075195, 0.26763486862182617, 0.25728297233581543]

I think scipy is sorting faster now....
