 `core-menu` is a selector which styles to looks like a menu.
 
     <core-menu selected="0">
       <core-item icon="settings" label="Settings"></core-item>
       <core-item icon="dialog" label="Dialog"></core-item>
       <core-item icon="search" label="Search"></core-item>
     </core-menu>

 When an item is selected the `core-selected` class is added to it.  The user can
 use the class to add more stylings to the selected item.
 
     core-item.core-selected {
       color: red;
     }
 
 The `selectedItem` property references the selected item.
 
     <core-menu selected="0" selectedItem="{{item}}">
