Added a "what's noodles" section.

  <h2>What's Noodles?</h2>
    <br>
    <h4>No, Noodles isn't that Japanese food you ate in college. It's an app where you can straighten out your recipes.
    <br>
    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.
