* Did not touch archived walkers... those can be named whatever.
* Kept abstract classes that end in Walker untouched (e.g. LocusWalker, ReadWalker, ...)
* Renamed a few inner classes due to conflict when stripping off Walker from their outer classes: ContigStats, FlagStats and FastaStats.
*New style.css, new template for the walker auto-generated html. Short description is no longer repeated in the long description of the walker.
*Updated DiffObjectsWalker and ContigStatsWalker as "reference" documented walkers.
DiffEngine fixed so that newInstance() would work. Pretty quickly encountered a situation where newInstance() failed. Debug output now written when this occurs in the log.
Logger now used instead of standard out, with INFO the default level.
Required a significant refactoring of the GATKDoclet, which now has a unified place where the ClassDoc, class, annotation, and handler are all stored together.
