David Smiley updated LUCENE-4645:
---------------------------------

    Attachment: LUCENE-4645__Spatial_Contains.patch

The attached patch implements the Contains algorithm for 
RecursivePrefixTreeStrategy; includes tests.

Unlike Intersects & Within, this one doesn't share the same tree visiting code, 
but it is also a recursive trie algorithm.  I expect for typical use cases that 
it'll be quite scalable and fast, though it does have to traverse all the way 
to the bottom detail at least once.

The existing test infrastructure made testing this easy.  The ~260 lines of 
often complicated code that implements the algorithm and miraculously it passed 
right away.  I upped the test repetitions to 1000 and set some break points at 
key points and indeed, it appears to work.  Today is a good day :-)

[~ryantxu], you seemed interested in getting ahold of this algorithm.  Do you 
want to test it on your data?  

I'll commit this in a couple days.
