      Description

      I think Lucene's current indexing chain has too many classes /
      hierarchy / abstractions, making it look much more complex than it
      really should be, and discouraging users from experimenting/innovating
      with their own indexing chains.

      Also, if it were easier to understand/approach, then new developers
      would more likely try to improve it ... it really should be simpler.

      So I'm exploring a pared back indexing chain, and have a starting patch
      that I think is looking ok: it seems more approachable than the
      current indexing chain, or at least has fewer strange classes.

      I also thought this could give some speedup for tiny documents (a more
      common use of Lucene lately), and it looks like, with the evil
      optimizations, this is a ~25% speedup for Geonames docs. Even without
      those evil optos it's a bit faster.

      This is very much a work in progress / nocommits, and there are some
      behavior changes e.g. the new chain requires all fields to have the
      same TV options (rather than auto-upgrading all fields by the same
      name that the current chain does)...
