This rework of Defects should be complete, so I'm putting it into review. Due to the size and number of ticket branches, I'm splitting up the review as follows:
Tim Jenness: Can you please look over the meas_algorithms and ip_isr changes?
Andrés Alejandro Plazas Malagón: Can you check the ci_cpp_gen2, ci_cpp_gen3, and cp_pipe changes?
Merlin Fisher-Levine: Can you check the remaining branches: ci_hsc_gen2, daf_butler, obs_base, obs_cfht, obs_decam, obs_lsst, obs_subaru, obs_test, and pipe_tasks?
As always, if you want to look over other packages, please do so. I didn't want to dump to much review on any one person.
I'm also not in a great rush on this, as I'll be taking a few days off this week.
