/**
 * `iron-meta` is a generic element you can use for sharing information across the DOM tree.
 * It uses [monostate pattern](http://c2.com/cgi/wiki?MonostatePattern) such that any
 * instance of iron-meta has access to the shared
 * information. You can use `iron-meta` to share whatever you want (or create an extension
 * [like x-meta] for enhancements).
 *
 * The `iron-meta` instances containing your actual data can be loaded in an import,
 * or constructed in any way you see fit. The only requirement is that you create them
 * before you try to access them.
 *
 * Examples:
 *
 * If I create an instance like this:
 *
 *     <iron-meta key="info" value="foo/bar"></iron-meta>
 *
 * Note that value="foo/bar" is the metadata I've defined. I could define more
 * attributes or use child nodes to define additional metadata.
 *
 * Now I can access that element (and it's metadata) from any iron-meta instance
 * via the byKey method, e.g.
 *
 *     meta.byKey('info');
 *
 * Pure imperative form would be like:
 *
 *     document.createElement('iron-meta').byKey('info');
 *
 * Or, in a Polymer element, you can include a meta in your template:
 *
 *     <iron-meta id="meta"></iron-meta>
 *     ...
 *     this.$.meta.byKey('info');
