Make parser run idiomatic ruby

[thatrubylove]

Love the project!

I would like to do a bunch of refactoring and test cleanup to make this more idiomatic. What do you guys think?

I will likely be making blog posts about the changes and possibly screencasts. There is some very nice code here, it just isn't very 'ruby'

I'm all for refactoring and learning how to do things the proper Ruby way so this sounds good. @alpaca-tc has also submitted some refactoring pull requests (https://github.com/nhmood/watson-ruby/pull/118) and has also suggested a refactor branch where these changes could be submitted (https://github.com/nhmood/watson-ruby/issues/127). I'm not sure how but I'll have to figure out a way to manage two separate refactorings going on at once.

I am definitely interested in the blog posts / screencast idea though, I think that would be a great resource not only for people but me as well :)

I have some functionality changes I'd like to get in and then I will revisit this refactoring issue.
