Description
The HSM shear estimation has received several improvements and important bugfixes on the HSC side that need to be ported to LSST. This is complicated by the fact that much of the code has been entirely rewritten on the LSST side to work within the new measurement framework, but we've also synchronized this package with the HSC side much more frequently than with other packages.

I accept Paul's statement that the unit test is adequate, though in general, I wish we have more complete tests for when we port algorithm changes.
I had two questions which are probably my lack of understanding of how the algorithms work. Please answer them, but if you are sure the code is right, go ahead and check in.
I think that the change to the unit test to add the centroid algorithm is my only actual complaint in this set of changes, so please see the pull request.
