## Use

When iterating over and array or list of items, you might need to render the index
of the item. Use the `@index` directive to do so. For example,

The template:

    <ul>
      {{#each items}}
        <li> {{@index}} - {{.}} </li>
      {{/each}}
    </ul>

Rendered with:

    { items: ['Josh', 'Eli', 'David'] }

Renders:

    <ul>
      <li> 0 - Josh </li>
      <li> 1 - Eli </li>
      <li> 2 - David </li>
    </ul>
