handle slicing as well as bucketed reductions
ahhh - numeric. That's how you do it.
more fixes.
can now generate a vector of dictionary keys for a set of feeds and map them to their event sources, and map that to a reduction.
Numeric stuff, comments, some easy new verbs (sample), some implicit conversions (got rid of need for queryE method)
cool, can now select a single column of a vector
more evolution, slight improvement in verb naming.
richer mekon tests, actually using it in anger now.
method name improvements.
Added more reduce / bucketing verbs to allow me to generate a report of median trade size by feed key for a set of trade feed configs.

removed the 'collapse' function, it was confusing, added a mapVector instead which satisfies all current usecases
name change
I wanted a vector subset for looking at some data in one of our raw feeds.
Rapid hack, I really need to start deleting some of the dead wood from this codebase (especially the java/scala division of code - I'm tempted to move much of the core into Java so that I can play with other languages, and so that my other pure-java code can use some of the utility)

Also added jfreechart integration, and a simple swingx jtable renderer for looking at output data.
