details: http://www.bx.psu.edu/hg/galaxy/rev/bed484895e2d changeset: 2721:bed484895e2d user: James Taylor james@jamestaylor.org date: Fri Sep 18 15:15:39 2009 -0400 description: More work on server side for tracks. Now uses converters instead of indexers. A wiggle to array_tree converter is provided. Still need to purge indexer stuff. This will not work without new bx egg (or likely at all)
