-/**
- * @group Polymer Core Elements
- *
- * The `core-iconset` element allows users to define their own icon sets. 
- * The `src` property specifies the url of the icon image. Multiple icons may
- * be included in this image and they may be organized into rows.
- * The `icons` property is a space separated list of names corresponding to the
- * icons. The names must be ordered as the icons are ordered in the icon image.
- * Icons are expected to be square and are the size specified by the `iconSize`
- * property. The `width` property corresponds to the width of the icon image 
- * and must be specified if icons are arranged into multiple rows in the image.
- *
- * All `core-iconset` elements are available for use by other `core-iconset`
- * elements via a database keyed by id. Typically, an element author that wants
- * to support a set of custom icons uses a `core-iconset` to retrieve 
- * and use another, user-defined iconset.
- *
- * Example:
- *
- *     <core-iconset id="my-icons" src="my-icons.png" width="96" iconSize="24"
- *         icons="location place starta stopb bus car train walk">
- *     </core-iconset>
- *
- * This will automatically register the icon set "my-icons" to the iconset
- * database.  To use these icons from within another element, make a 
- * `core-iconset` element and call the `byId` method to retrieve a
- * given iconset. To apply a particular icon to an element, use the 
- * `applyIcon` method. For example:
- *
- *     iconset.applyIcon(iconNode, 'car');
- *
- * Themed icon sets are also supported. The `core-iconset` can contain child
- * `property` elements that specify a theme with an offsetX and offsetY of the
- * theme within the icon resource. For example.
- *
- *     <core-iconset id="my-icons" src="my-icons.png" width="96" iconSize="24"
- *         icons="location place starta stopb bus car train walk">
- *       <property theme="special" offsetX="256" offsetY="24"></property>
- *     </core-iconset>
- *
- * Then a themed icon can be applied like this:
- *
- *     iconset.applyIcon(iconNode, 'car', 'special');
- *
- * @element core-iconset
- * @extends core-meta
- * @homepage github.io
