+/**
+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.
+
+### 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.

+Use `Polymer.PaperDialogBehavior` and `paper-dialog-common.css` 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>
+    </paper-dialog-impl>
+
+`paper-dialog-common.css` 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"`. The header (a `<h2>` element) will
+
+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.

+   *
+   * 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="50" y="50" width="50" height="50" />

+   *         </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:
+   *

+ *
+ * We write out each animation in full (instead of separating animation-name,
+ * animation-duration, etc.) because under the polyfill, Safari does not recognize those

+ * other animation rules. See https://github.com/Polymer/platform/issues/53.
