basic design for home screen...

Hey guys, 

I was just messing around with Bootstrap tonight, and put this basic view for the home screen together.
Please feel free to change it in any way you see fit. I do like having some kind of nice placeholder on the start screen for where the breath drawing canvas will be (after the user hits start), which in this design is a  meditation image. Right now, when the user clicks on this image, a set of instructions pop up, so first-time users don't get confused.

Functionality:
Implements basic layout for home screen, and adds a small js file for basic home screen interaction.
