  /**
  `iron-selector` is an element which can be used to manage a list of elements
  that can be selected.  Tapping on the item will make the item selected.  The `selected` indicates
  which item is being selected.  The default is to use the index of the item.

  Example:

      <iron-selector selected="0">
        <div>Item 1</div>
        <div>Item 2</div>
        <div>Item 3</div>
      </iron-selector>

  If you want to use the attribute value of an element for `selected` instead of the index,
  set `attrForSelected` to the name of the attribute.  For example, if you want to select item by
  `name`, set `attrForSelected` to `name`.

  Example:

      <iron-selector attr-for-selected="name" selected="foo">
        <div name="foo">Foo</div>
        <div name="bar">Bar</div>
        <div name="zot">Zot</div>
      </iron-selector>

  You can specify a default fallback with `fallbackSelection` in case the `selected` attribute does
  not match the `attrForSelected` attribute of any elements.

  Example:

        <iron-selector attr-for-selected="name" selected="non-existing"
                       fallback-selection="default">
          <div name="foo">Foo</div>
          <div name="bar">Bar</div>
          <div name="default">Default</div>
        </iron-selector>

  Note: When the selector is multi, the selection will set to `fallbackSelection` iff
  the number of matching elements is zero.

  `iron-selector` is not styled. Use the `iron-selected` CSS class to style the selected element.

  Example:

      <style>
        .iron-selected {
          background: #eee;
        }
      </style>

      ...

      <iron-selector selected="0">
        <div>Item 1</div>
        <div>Item 2</div>
        <div>Item 3</div>
      </iron-selector>
