Refactor/split into multiple files

[clehner]

As the script is now >1000 lines and embracing several areas of functionality, @jeremywrnr and I were discussing splitting it into separate files. We propose keeping core functions (like get courses) and command line argument parsing in bb while making one file for each command (except commands where there is significant overlap).

This could be done in such a way that only the scripts which need to be executed are sourced. e.g.

case "$cmd" in
...
bill) source $BB_PATH/quikpay; bb_bill $@;;
...

I was going to suggest the same thing. Sounds like a great idea to me.

import.sh repo here is interesting and may be useful for dealing with this issue.
