Adds a Builder class for STRtree and for SIRtree, separating the building from querying of the tree. See the mailing list for discussion about this. I also made a bunch of things deprecated in anticipation that eventually these classes will ditch insert() & build().
I also made some optimizations in remove() to use iterator.remove() which apparently the original author didn't know...
