-// Action links are elements that are used to perform an in-page navigation or
-// action (e.g. showing a dialog).
-//
-// They look like normal anchor (<a>) tags as their text color is blue. However,
-// they're subtly different as they're not initially underlined (giving users a
-// clue that underlined links navigate while action links don't).
-//
-// Action links look very similar to normal links when hovered (hand cursor,
-// underlined). This gives the user an idea that clicking this link will do
-// something similar to navigation but in the same page.
-//
-// They can be created in JavaScript like this:
-//
-// var link = document.createElement('a', 'action-link'); // Note second arg.
-//
-// or with a constructor like this:
-//
-// var link = new ActionLink();
-//
-// They can be used easily from HTML as well, like so:
-//
-// <a is="action-link">Click me!</a>
-//
-// NOTE: <action-link> and document.createElement('action-link') don't work.

-/**
- * 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
- * @demo demo/index.html
- * @implements {Polymer.Iconset}

-/**
-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.
-
-See the [demo source code](https://github.com/PolymerElements/iron-overlay-behavior/blob/master/demo/simple-overlay.html)
-for an example.
-
-### Closing and canceling
-
-An overlay 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.
-
-In addition, `with-backdrop` will wrap the focus within the content in the light DOM.
-Override the [`_focusableNodes` getter](#Polymer.IronOverlayBehavior:property-_focusableNodes)
-to achieve a different behavior.
-
-### 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.

-`<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.
-
- \x3c!-- only allow characters that match [0-9] --\x3e
- <input is="iron-input" prevent-invalid-input allowed-pattern="[0-9]">
