      Description

      Our current version of Eigen is 3.2.5, which does not support CholmodBase.determinant(), which I would like to have for debugging jointcal. I suspect it will bring in a variety of other updates we will want to use in jointcal and afw.

      I fear that this won't be a trivial upgrade: there have been quite a few releases between 3.2.5 and 3.3.4:

      http://eigen.tuxfamily.org/index.php?title=ChangeLog#Eigen_3.3-alpha1

      My first naive attempt to build and use a new Eigen with jointcal resulted in a slew of ndarray errors, so there's going to be some C++/ndarray upgrade work to make this happen.
