Added a "what's noodles" section.

## What's Noodles?
*No, Noodles isn't that Japanese food you ate in college. It's an app where you can straighten out your recipes.*
Remember that delicious pie your mom made? Remember where the recipe is for it? Thought so. Noodles lets you take a picture of your recipe and with a SNAP, the recipe is made into text and sent to our servers and Evernote. So you can relive childhood, one bite at a time.
