Schedule reminder

Hey guys, just wanted to let you know a few things...

First off, I just wanted to commit this part...I've got a few Rspec tests working and the basics for creating my rake task are complete...I just want to run a few tests locally from our app before I say that it is working for sure.

Other things...I ran into some weird bugs at the end of the day when I pulled down our code. I found that the  challenge_helper needed to be wrapped in a module. I also got some errors with the way we were configuring Twitter in environment.rb, so I changed it to the new format as outlined in the Twitter API documentation in order to make it work.
