Assignment #4 - Functional Traffic Light - Feedback

Good work man! Traffic light looks good, functions well, and your html and javascript code is very well written. Your client would be happy!

A few notes:
- I tweaked some of the indentation and tag nesting in your HTML file.
- I re-organized your CSS code so that the least specific rules were at the top.
- I added a few suggestions to your JavaSCript code. For first time JavaScript writing though, your JS file is fantastic.
