[Chicago] Chance to try out AppEngine (and make my life easier)

The database is rather small and it was not such a difficult project  
using web2py (99 lines of code) so I just made it.
Turns out the use of SQL IN and LIKE operators are crucial for this  
project and they are not supported by google appengine.
You should pick another project for that purpose.

Anyway, you can try it here


I did not try to fix the typos in the town names as they appear on  
their online schedule. It is a bit slow because I have not yet  
created the db indices.
Do you think Metra may want to buy it? You got the idea, so you get 20%.
