Material Design: [Chips](http://www.google.com/design/spec/components/chips.html)

`paper-chip` Chips represent complex entities in small blocks, such as a contact.
They can contain a photo, short title string, and brief information.

## Examples:

deletable chip with iron-icon

    <paper-chip label="John Doe" deletable>
      <iron-icon class="icon" icon="android"></iron-icon>
    </paper-chip>

Basic chip with single letter instead of an icon

    <paper-chip label="Jane Doe">
      <div class="icon">J</div>
    </paper-chip>

Setting the height of a chip:

    <style>
      paper-chip.small {
        --paper-chip-height: 24px;
      }
    </style>

    ...

    <paper-chip label="Jane Doe" class="small">
      <div class="icon">J</div>
    </paper-chip>
-->
