I'd suggest a three panel plot: ray traced kappa, halo model-predicted kappa, difference, to illustrate the quantitative findings coming from #94 - what do you think?

This can now be done with the compare_binned_maps() method in plotting.py, given two binned kappamaps that result from running bin_to_map() using lens-by-map and lens-by-halo ellipticities.

Here's an example:
kappamaps2
where the left is a binned Hilbert map, the center is the predicted binned kappamap, and the right is the difference of the two maps. All images use the same intensity mapping. Analysis of results is in issue #94 .
