`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
is highlighted, and the selected item has bolded text.
    <paper-menu>
      <paper-item>Item 1</paper-item>
      <paper-item>Item 2</paper-item>
    </paper-menu>
An initial selection can be specified with the `selected` attribute.
    <paper-menu selected="0">
      <paper-item>Item 1</paper-item>
      <paper-item>Item 2</paper-item>
    </paper-menu>
Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
and multiple item can be selected.
    <paper-menu multi>
      <paper-item>Item 1</paper-item>
      <paper-item>Item 2</paper-item>
    </paper-menu>

`--paper-menu-color`               | Menu foreground color                                            | `--primary-text-color`

`--paper-menu-selected-item`      | Mixin applied to the selected item                               | `{}`
`--paper-menu-focused-item`       | Mixin applied to the focused item                                | `{}`

### Accessibility
`<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
`aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
of a menu item will also focus it.
