While single number point estimates are bad for actual photo-z use in science, they can be useful as diagnostics, so add calculations of point_sigma_IQR, point_bias, and point_cat_outlier_rate to the code

The skgof module is not maintained anymore. import skgof gives:

/usr/local/anaconda3/lib/python3.7/site-packages/skgof/ecdfgof.py:45: FutureWarning: arrays to stack must be passed as a "sequence" type such as list or tuple. Support for non-sequence iterables such as generators is deprecated as of NumPy 1.16 and will raise an error in the future.

The checkmark sign \u2713 in the verbose version causes an error in the terminal for some users.

UnicodeEncodeError: 'ascii' codec can't encode character '\u2713' in position 7: ordinal not in range(128)

We should probably remove it from the code, It doesn't seem necessary.

We might need to improve the efficiency of FoF matching. @sschmidt23 suggested this obvious speedup: for each tract, only load the overlapping healpix pixels, and save the match 1:1, 2:1, and 3:1 matched catalogs as hdf5 or parquet output by pandas once you combine them into a single data frame after matching

Since dereddened magnitudes are not available from the GCR by default, add either a few cells showing how to deredden using dustmaps, or create a method in the base class that performs dereddening

we have settled on arranging the pz-blend plots three in a row style. when they are shrunk down this small, the fontsize for the legend is a bit too small. adjust the fontsize so it is comperable to caption fontsize

The code could benefit from some docstrings.

write something that will dump out all the statistics we could be interested in
ks test for PIT values
ks test for empirical specz and stacked pz
others?

it's a list of commands right now, ideally it will be tidied up

Running setup.py gives the following error:

We need to disable the javascript version of the progress bar if ipywidgets is not installed, even though in such cases it will throw a helpful error message providing instructions on how to install it: https://ipywidgets.readthedocs.io/en/stable/user_install.html

We should also set a way to run without the progress bar for people that don't like it for whatever reason.

How about adding ipywidgets to install_requires in setup.py?
