Workin on the eval package
Merge branch 'master' of https://github.com/CIIR/julien
Finished first cut of the evaluation package in Julien. Want to refactor the Accumulators to produce QueryResult objects. That's on the list.
Removed the ExtentArrayIterator, finished a very minor refactor of OD and UW. They could be faster, but the code to do so would be ugly. Think on it first.
Removed the positions wrapper; added iterator functionality directly to the extent array; identified the scala priority queue as a liability for now
