Python libraries

[Zarquan]

Should we create a Python library of common tools that we use all the time. That way we can just import the library into our notebooks and programs and always get the same thing.

I'm thinking of things like the schema for the various catalog imports, the steps for doing the import and the verifying the results afterwards. I've seen each of us import the Gaia and 2MASS data several times in different notebooks as part of our development work testing the different filesystems. Each time we have a large chunk of Python code setting up the catalog schema. Danger is that large chunk of code gets copied and pasted multiple times without getting checked for accuracy.
