-   * The `<platinum-sw-cache>` element makes it easy to precache specific resources, perform runtime

-   * Under the hood, the [sw-toolbox](https://github.com/googlechrome/sw-toolbox) library is used
-   * for all the caching and request handling logic.
-   * `<platinum-sw-cache>` needs to be a child element of `<platinum-sw-register>`.
-   * A simple, yet useful configuration is
-   *
-   *     <platinum-sw-register auto-register>
-   *       <platinum-sw-cache></platinum-sw-cache>
-   *     </platinum-sw-register>
-   *
-   * This is enough to have all of the resources your site uses cached at runtime, both local and
-   * cross-origin.
-   * (It uses the default `defaultCacheStrategy` of "networkFirst".)
-   * When there's a network available, visits to your site will go against the network copy of the
-   * resources, but if someone visits your site when they're offline, all the cached resources will
-   * be used.

-       * attributes. This can come in handy when the configuration (e.g. which files to precache)
-       * depends on the results of a build script.
-       *
-       * If configuration for the same properties are provided in both the JSON file and via the
-       * element's attributes, then in general the JSON file's values take precedence. The one
-       * exception is the `precache` property. Any values in the element's `precache` attribute will
-       * be concatenated with the values in the JSON file's `precache` property and the set of files
-       * that are precached will be the union of the two.
-       *
-       * There's one additional option, `precacheFingerprint`, that can be set in the JSON. If using
-       * a build script that might output a large number of files to precache, its recommended
-       * that your build script generate a unique "fingerprint" of the files. Any changes to the
-       * `precacheFingerprint` value will result in the underlying service worker kicking off the
-       * process of caching the files listed in `precache`.
-       * While there are a few different strategies for generating an appropriate
-       * `precacheFingerprint` value, a process that makes sense is to use a stable hash of the
-       * serialized `precache` array. That way, any changes to the list of files in `precache`
-       * will result in a new `precacheFingerprint` value.
-       * If your build script is Node.js based, one way to generate this hash is:
-       *
-       *     var md5 = require('crypto').createHash('md5');
-       *     md5.update(JSON.stringify(precache));
-       *     var precacheFingerprint = md5.digest('hex');

-       * Alternatively, you could use something like the
-       * [SHA-1 signature](http://stackoverflow.com/questions/1161869/how-to-get-sha-of-the-latest-commit-from-remote-git-repository)
-       * of your latest `git` commit for the `precacheFingerprint` value.
-       *
-       * An example file may look like:
-       *
-       *     {
-       *       "cacheId": "my-cache-id",

-/**
-Use `Polymer.IronOverlayBehavior` to implement an element that can be hidden or shown, and displays
-on top of other content. It includes an optional backdrop, and can be used to implement a variety
-of UI controls including dialogs and drop downs. Multiple overlays may be displayed at once.
-
-### Closing and canceling
-
-A dialog may be hidden by closing or canceling. The difference between close and cancel is user
-intent. Closing generally implies that the user acknowledged the content on the overlay. By default,
-it will cancel whenever the user taps outside it or presses the escape key. This behavior is
-configurable with the `no-cancel-on-esc-key` and the `no-cancel-on-outside-click` properties.
-`close()` should be called explicitly by the implementer when the user interacts with a control
-in the overlay element. When the dialog is canceled, the overlay fires an 'iron-overlay-canceled'
-event. Call `preventDefault` on this event to prevent the overlay from closing.
-
-### Positioning
-
-By default the element is sized and positioned to fit and centered inside the window. You can
-position and size it manually using CSS. See `Polymer.IronFitBehavior`.
-
-### Backdrop
-
-Set the `with-backdrop` attribute to display a backdrop behind the overlay. The backdrop is
-appended to `<body>` and is of type `<iron-overlay-backdrop>`. See its doc page for styling
-options.
-
-### Limitations
-
-The element is styled to appear on top of other content by setting its `z-index` property. You
-must ensure no element has a stacking context with a higher `z-index` than its parent stacking
-context. You should place this element as a child of `<body>` whenever possible.

-   * The `iron-iconset-svg` element allows users to define their own icon sets
-   * that contain svg icons. The svg icon elements should be children of the
-   * `iron-iconset-svg` element. Multiple icons should be given distinct id's.
-   *
-   * Using svg elements to create icons has a few advantages over traditional
-   * bitmap graphics like jpg or png. Icons that use svg are vector based so
-   * they are resolution independent and should look good on any device. They
-   * are stylable via css. Icons can be themed, colorized, and even animated.
-   *
-   * Example:
-   *
-   *     <iron-iconset-svg name="my-svg-icons" size="24">
-   *       <svg>
-   *         <defs>
-   *           <g id="shape">
-   *             <rect x="12" y="0" width="12" height="24" />
-   *             <circle cx="12" cy="12" r="12" />
-   *           </g>
-   *         </defs>
-   *       </svg>
-   *     </iron-iconset-svg>
-   *
-   * This will automatically register the icon set "my-svg-icons" to the iconset
-   * database.  To use these icons from within another element, make a
-   * `iron-iconset` element and call the `byId` method
-   * to retrieve a given iconset. To apply a particular icon inside an
-   * element use the `applyIcon` method. For example:
-   *
-   *     iconset.applyIcon(iconNode, 'car');

-   * @element iron-iconset-svg

-/**
-Use `Polymer.PaperDialogBehavior` and `paper-dialog-shared-styles.html` to implement a Material Design
-dialog.
-
-For example, if `<paper-dialog-impl>` implements this behavior:
-
-    <paper-dialog-impl>
-        <h2>Header</h2>
-        <div>Dialog body</div>
-        <div class="buttons">
-            <paper-button dialog-dismiss>Cancel</paper-button>
-            <paper-button dialog-confirm>Accept</paper-button>
-        </div>
-    </paper-dialog-impl>
-
-`paper-dialog-shared-styles.html` provide styles for a header, content area, and an action area for buttons.
-Use the `<h2>` tag for the header and the `buttons` class for the action area. You can use the
-`paper-dialog-scrollable` element (in its own repository) if you need a scrolling content area.
-
-Use the `dialog-dismiss` and `dialog-confirm` attributes on interactive controls to close the
-dialog. If the user dismisses the dialog with `dialog-confirm`, the `closingReason` will update
-to include `confirmed: true`.
-
-### Styling
-
-The following custom properties and mixins are available for styling.
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-dialog-background-color` | Dialog background color                     | `--primary-background-color`
-`--paper-dialog-color`            | Dialog foreground color                     | `--primary-text-color`
-`--paper-dialog`                  | Mixin applied to the dialog                 | `{}`
-`--paper-dialog-title`            | Mixin applied to the title (`<h2>`) element | `{}`
-`--paper-dialog-button-color`     | Button area foreground color                | `--default-primary-color`
-
-### Accessibility
-
-This element has `role="dialog"` by default. Depending on the context, it may be more appropriate
-to override this attribute with `role="alertdialog"`.
-
-If `modal` is set, the element will set `aria-modal` and prevent the focus from exiting the element.
-It will also ensure that focus remains in the dialog.
-
-The `aria-labelledby` attribute will be set to the header element, if one exists.

-`<iron-input>` adds two-way binding and custom validators using `Polymer.IronValidatorBehavior`
-to `<input>`.
-
-### Two-way binding
-
-By default you can only get notified of changes to an `input`'s `value` due to user input:
-
-    <input value="{{myValue::input}}">
-
-`iron-input` adds the `bind-value` property that mirrors the `value` property, and can be used
-for two-way data binding. `bind-value` will notify if it is changed either by user input or by script.
-
-    <input is="iron-input" bind-value="{{myValue}}">
-
-### Custom validators
-
-You can use custom validators that implement `Polymer.IronValidatorBehavior` with `<iron-input>`.
-
-    <input is="iron-input" validator="my-custom-validator">
-
-### Stopping invalid input
-
-It may be desirable to only allow users to enter certain characters. You can use the
-`prevent-invalid-input` and `allowed-pattern` attributes together to accomplish this. This feature
-is separate from validation, and `allowed-pattern` does not affect how the input is validated.
-
-    <!-- only allow characters that match [0-9] -->
