> Examples work again.
> * removed dependency on Guava (which it didn't actually depend on) and on Piggybank (since
date functions are now first class)
> * path to datafu jar correct for current repo layout
> * The quantile examples demonstrate a comparison of the exact vs approx algorithms (my
first question was "how approximate is approximate?" 0.5% to 1.5% on the little drip of data
that's using)
> * added the script to generate data for quantile and a frozen version of 30k records.
> * Quantile examples demonstrate both ways of constructing a Quantile UDF (number of partitions
vs list of breakpoints)
> There are _two_ patches attached. One adds a 30k-line data file. The other holds the
changes to the code and so forth.
