I've started looking into reading in and using weak lensing data with Pangloss. We can use this pull request to track changes in the wl branch.

…ground objects with `importance` greater than the kwarg `importance_lim`, which by default is set to 0.0 (so all galaxies are used). #66
…the method is not making the lensing process noticably faster. #66
…s and definitions to be placed. The first script is called `lens_compare.py` which creates a `BackgroundCatalog`, lenses it by `WLMap`s and halos, and then compares the correlation of each.
…oundCatalog` to correctly calculate the strongly-lensed ellipticity if g>1. However, `lens_by_map()` currently removes all galaxies with a g>0.5. #58

I am amazed that this branch can be merged cleanly. @tcollett @charlottenosam what criteria would you like us to meet before merging all this weak lensing work into the Pangloss master branch? At the moment the basic Pangloss test does not work, because the data is not quite in the right place ( #11 ), but I am worried that when we merge in from the wl branch, it will become difficult/impossible to reproduce your two papers. Thoughts welcome! Are you planning on using the Pangloss code in the near future? Are you using it now?

….py`, `plotting.py`, and the `lens_compare` test that I used in the final days of finishing my thesis. I must have forgotten one final push - oops! The only major changes were finishing the implementation of the log-likelihood calculation in `background`, pre-calculating the redshift bin volumes (implemented in `grid` and called in `background`) to speed up the smooth-component correction, and a few plotting changes in `plotting` for better plots to use in my thesis. I dont think this should conflict much (or at all) with what David has started to work on. Sorry for any confusion! #73 #101
