-modularized javascript in html
-added polymer sandbox, including core components folder and some html boilerplate
-copied entire public folder into the sandbox. if we decide to use the changes made to this public folder, we can just overwrite the old one.
-to use, run grunt like normal, except you will navigate to http://localhost:8000/polymer/index.html instead. It is important to know that some paths are now relative to the new location of index. For instance, the action of the upload form is now fully qualified in order to trigger the built-in upload route.
-this index incorporates fancy box, which is the way i think uploads should take place. it prevents the cluttering of our page.
-changed the main dropzone_init.js to do animations when a file is received, instead of when it is only dropped by the user.
-updated word histogram, added vocabulary count, added search for user by name
-added polymer index.html
-added polymer components and fancybox
