added to 3.x.

>> A tool to sort index according to a float document weight. Documents with high weight
are given low document numbers, which means that they will be first evaluated. When using
a strategy of "early termination" of queries (see TimeLimitedCollector) such sorting significantly
improves the quality of partial results.

weights - thus the ordering was limited by the limited resolution of norms. This is a pure
Lucene version of the tool, and it uses arbitrary floats from a specified stored field).
