+ * Mustache Template array Loader implementation.
+ *
+ * An ArrayLoader instance loads Mustache Template source by name from an initial array:
+ *
+ *     $loader = new ArrayLoader(
+ *         'foo' => '{{ bar }}',
+ *         'baz' => 'Hey {{ qux }}!'
+ *     );
+ *
+ *     $tpl = $loader->load('foo'); // '{{ bar }}'
+ *
+ * The ArrayLoader is used internally as a partials loader by Mustache_Engine instance when an array of partials
+ * is set. It can also be used as a quick-and-dirty Template loader.
+ *
