Feature request: Change labels in plots

[leocasarsa]

It is usually more practical to handle short variable names while doing analysis, but to write the full variable description in plots.

For examples, it is easier to write q(''' SELECT PRD_MIN FROM %t'''), instead of "Period in Minutes", while the latter name is more informative in a pairplot or heatmap.

One solution would be to pass a codebook df or csv to the make_population command and have the plots access the codebook instead. However it might also be useful to keep the ability of plotting with labels such as PRD_MIN for succint preliminary analyses purposes.

The cumbersome alternative right now is to redefine the variable names and retraining the metamodel to change the labels. Definitely not optimal.

There is some facility for this in bayeslite: https://github.com/probcomp/bayeslite/blob/master/src/codebook.py

We could wrap this better in bdbcontrib, but let me check if you can get it to do the thing you want.
