IR static methods
I have a strong desire to remove all these static methods from IR -
lastModified, getCurrentVersion, getCommitUserData, indexExists.
But haven't found a good place for them yet.
Directory - is a bad place, it shouldn't concern itself with details
of what exactly is stored inside, it should think of 'how' it is
stored.
IndexReader - is bad, it is too heavyweight to be created for getting
something simple once.
We should probably create some new lightweight class that provides a
kind of reflection for the index? Mod dates, versions, userdata,
existence, sizes, deletions, whatever. Both per-index and per-segment.
Essentially it is a wrapper over SegmentInfos that allows us to keep
them hidden (and thus easily changeable), and provides users with more
concise and adequate interface.
Any thoughts?

Index/Commit/SegmentMetadata? Several classes, as you can reflect on
various levels of the index.
Some offtopic - SegmentInfo/SegmentsInfo should really be named
Segment/Segments. That's exactly what these objects represent.
You don't use names like PreparedStatementInfo or FileInfo or IntegerInfo :)
