Davis King c1343f0754 Switched the sparse vectors all over to unsigned integral keys and changed 
the definition of what is officially a sparse vector to say that unsigned
integral keys are required.  Having this requirement is nice because it creates
a simple correspondence between dense vector index values and sparse vector keys.
The previous sparse vector definition was just excessively generic.

Davis King b77ee4307a This change was just to avoid a warning from gcc. The code still 
computes exactly the same thing as before.
