Despite the title of the ticket, only the creation of the two Deblend... classes and the additions to obs_base were required by the new deblender. The rest were caused by gradual changes to pipe_tasks that I hadn't caught until trying to re-run older code.

Also, please note that pipe_tasks does not show up in the pull requests link, but does have a pull request. That package has so many pull requests that JIRA has stopped trying to link them.

My only concern was that the obs_base changes look to have a typo that defined deepCoadd_deblendedModel twice.  Everything else looks good.
