ANetAstrometryTask and all other astrometry.net-related code has moved from
meas_astrom into a new package
meas_extensions_astrometryNet, along with all lower-level DM code that depends on astrometry.net.. The APIs have not changed..
For now ANetAstrometryTask is still the default astrometry solver, so
pipe_tasks depends on
meas_extensions_astrometryNet. Once we change that default (on DM-10242) we can remove that dependency. I don't know when we will consider ourselves ready to do that.
This split was made on DM-2186 and merged to master on 2014-04-28.
