add pyquery as it's a requirement for load_enrollment
update load_enrollment to use output using logging so I can see what it's doing
document where a human would find this enrollment data
move chattier logging to DEBUG level so INFO is more readable
fix, it is not 2011
stop displaying south debug logs
begin adding tests to stupid enrollment data functionality
document how the 'total' number is bunk
prep for getting fte info from thecb
fix all the data inconsistencies in the enrollment buckets
begin documenting data quirks in one place

I feel like I was repeating myself trying to explain quirks every
place in the code.
document some enrollment data quirks
refactor homepage to not need context_data injection
throw thecb data out of get_short_list since we can't get fte values from them
refactor short list logic to use no custom code
document how to debug missing fte data
document edge cases

I don't know what to do with these. Just documenting these so I can
consult with experts easier later.
document the different categories each thecb tool gives you
