Code review comment for lp:~thumper/launchpad/bmp-index-faster

I notice neither DecoratedBug nor DecoratedBranch have docstrings, nor do they define an interface making them inscrutable. This is particularly confusing for DecoratedBug which provides self.tasks, self.bugtasks, self.bugtask, self.getBugTask(), self.default_bugtask - some of these are synonyms and some of them (getBugTask() and bugtask) return different things despite their names indicating the are synonyms.

We can let this slide on this branch though since this is moving code to a better location, so a net win. It would be nice to merge the synonyms and document things though if possible.

Otherwise all fine.
