This app scrapes the Columbus Chiller website schedule for data. See http://www.thechiller.com/rink-schedule

==
USAGE EXAMPLES

Get all schedule data for today:
http://chiller.heroku.com

Get only Stick and Puck events on the schedule:
http://chiller.heroku.com/StickAndPuck
or
http://chiller.heroku.com/?filter=stick and puck

History and Future refactoring ideas:

Originally I was only going to scrape the website for only "Stick and Puck" events.  When it got to the point of
refactoring to filter out everything but Stick and Puck, I decided to leave the default get '/' to go ahead and
get all events on the schedule.  Then I added a separate action /StickAndPuck to get those.  Further refactoring
led to being able to pass a filter String in the query string parameters, for example: 
http://chiller.heroku.com/?filter=stick and puck

Originally I was not going to allow the user to input a date on the query string.  Then I came across a bug that
only shows up after midnight, and seems to last until 3am (suggesting perhaps their servers are in the PST time
zone).  For example: on 10/19/11 the data was properly scraped for the 19th.  At 12:00 AM on 10/20/11 when you
visit http://www.thechiller.com/rink-schedule it is still showing data for the 19th by default.  But the app
tries to get data for Time.now which didn't work early morning on the 20th.  It was easiest to allow a query
string date to be entered for these situations, then I didn't have to hardcode it when testing.  To use this go
to http://chiller.heroku.com/?date=2011-10-20.  This change made testing easier, too. 

I did not list this in the "usage" section above because it's misleading to think you could enter ANY date at all
and get the schedule for that day.  Eventual refactoring could lead to being able to use the query string
date parameter to change the date in the request to the schedule and get data for different dates (simulating
the request that happens when choosing different dates in the drop-down box and clicking "go").

Eventual refactoring, once the app gets much bigger, would extract private methods from schedule.rb into helpers
or just into a separate class.
