Description
Use ImageMapReduce to implement a spatially-varying A&L decorrelation task. Integrate that task as an option in imageDifference.py.
Will possibly want to implement it as a subclass of ImagePsfMatchTask, because that task includes wrapper code for warping, which will be necessary here.
I've updated the code in order to (hopefully) address all PSF sizing issues. I also added a unit test that explicitly checked for cases where the PSFs had different dimensions. This code is now checked in.
I'll attempt to re-run your tests on lsst-dev now.
