Add presentations for talks given at Polytechnic event at Google Seattle, November 15, 2014

Here are two talks I gave at the Polytechnic event at Google's office in Seattle. These talks did *not* use the stock slide decks provided for the event. Instead, both are live code demos written from scratch for the event.

1. The first talk is an intro to web components. It walks through the significance of the relevant specs through code examples. For this talk, it was fun to show *native* components first in Chrome, then tackle webcomponents.js only later in the talk when discussing older browsers!
2. The second talk is a more advanced one covering some patterns for component reuse. This covers four examples in live code. The third example, a monthly calendar component, introduces a new, general pattern for highly reusable components.
