--------------------------------------------------------------
After talking offline to Ted, I made the following changes:
- moved the classes from o.a.m.clustering.streaming.search to
o.a.m.math.neighborhood; the class need to remain in core/ because they depend
on the distance measures which are in core/ (and those cannot be moved to math/
because of Hadoop dependencies)
- moved lumpyRandomData() to LumpyData
- made SearchQualityTest a value-parameterized test that compares different
searchers' best result to the brute searcher's result and compares runtimes

> Project: Mahout
> Issue Type: New Feature
> Components: Clustering
> Affects Versions: 0.8
> Reporter: Dan Filimon
> Attachments: MAHOUT_1156.patch, MAHOUT_1156_tests.patch

>
> Adding the Searcher, UpdatableSearcher abstract classes defining what a
> nearest-neighbor searcher does.
> The following implementations are available in the o.a.m.math.neighborhood
> package:
> - BruteSearch
> - ProjectionSearch
> - FastProjectionSearch
> - LocalitySensityHashSearch
> Additionally there are 2 new abstract classes available:
> - Searcher
> - UpdatableSearcher
> This is part of https://issues.apache.org/jira/browse/MAHOUT-1154
> There are no more test issues.
