Cantina Excercise Build

Cantina, 

I built the requested To Do application using HTML, Stylus, and Angular.js. I apologize for the large pull request; I used grunt to compile my css and forgot to un-track the node modules.

Thank you for the opportunity to do this exercise. I look forward to any additional steps in your interview process and ultimately for the opportunity to work with such a talented team. 

Thank you, 

Aaron A. Pollock
