workaround

As a workaround, I created a fresh project and the example works as expected now. Here is what I did.

• Installed Polymer 0.3.3 with Bower.
• Copied the tutorial application files and modified relative paths appropriately.

@arthurevans can you take a look?

Thanks. The components packaged with the tutorial were out of sync. This should be fixed in the polymer - tutorial repo now.
