Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Button</a>

`paper-fab` is a floating action button. It contains an image placed in the center and
comes in two sizes: regular size and a smaller size by applying the attribute `mini`. When
the user touches the button, a ripple effect emanates from the center of the button.

You may import `iron-icons` to use with this element, or provide a URL to a custom icon.
See `iron-iconset` for more information about how to use a custom icon set.

Example:

    <link href="path/to/iron-icons/iron-icons.html" rel="import">

    <paper-fab icon="add"></paper-fab>
    <paper-fab mini icon="favorite"></paper-fab>
    <paper-fab src="star.png"></paper-fab>


### Styling

The following custom properties and mixins are available for styling:

Custom property | Description | Default
----------------|-------------|----------
`--paper-fab-background` | The background color of the button | `--accent-color`
`--paper-fab-keyboard-focus-background` | The background color of the button when focused | `--paper-pink-900`
`--paper-fab-disabled-background` | The background color of the button when it's disabled | `--paper-grey-300`
`--paper-fab-disabled-text` | The text color of the button when it's disabled | `--paper-grey-500`
`--paper-fab` | Mixin applied to the button | `{}`
`--paper-fab-mini` | Mixin applied to a mini button | `{}`
`--paper-fab-disabled` | Mixin applied to a disabled button | `{}`
