  16   *
  17   *     $loader = new ArrayLoader(
  18   *         'foo' => '{{ bar }}',
  19   *         'baz' => 'Hey {{ qux }}!'

  21   *

  23   *
  24   * The ArrayLoader is used internally as a partials loader by Mustache_Engine instance when an array of partials
  25   * is set. It can also be used as a quick-and-dirty Template loader.
