[Chicago] Parsing Metra's Online Schedule

[Massimo Di Pierro]

The Metra schedule already parsed and normalized in routes is here:

     http://mdp.cti.depaul.edu/examples/static/metra.pickle

[(line,type,routes),...]

type=1 for weekdays, 2 for saturday and 3 for sundays
routes is {route_number:[(station,time),(station,time),...],...}

time is in minutes from midnight.

Getting this was not as easy as it seems and took a lot of work.
