paper-button
============
Material Design: Buttons
`paper-button` is a button. When the user touches the button, a ripple effect emanates
from the point of contact. It may be flat or raised. A raised button is styled with a
shadow.
Example:
```html
flat button
raised button
No ripple effect
```
You may use custom DOM in the button body to create a variety of buttons. For example, to create a button with an icon and some text:
```html
custom button content
```
