- The code has been completely restructured from a single `import.py` script to load and create the supernovae catalog, into two separate packages (and corresponding repositories): [astrocatalogs/AstroCats](https://github.com/astrocatalogs/astrocats), and the supernova-specific [astrocatalogs/Supernovae](https://github.com/astrocatalogs/supernovae).
- This package, `astrocats`, contains the core machinery for creating any general, astronomical catalog. In particular, the `astrocats/catalog` directory contains the base set of classes which provide all of the desired functionality.
