13	* Mustache Template filesystem Loader implementation.
14	*
15	* A FilesystemLoader instance loads Mustache Template source from the filesystem by name:
16	*
17	* $loader = new Mustache_Loader_FilesystemLoader(dirname(__FILE__).'/views');
18	* $tpl = $loader->load('foo'); // equivalent to `file_get_contents(dirname(__FILE__).'/views/foo.mustache');
19	*
20	* This is probably the most useful Mustache Loader implementation. It can be used for partials and normal Templates:
21	*
22	* $m = new Mustache(array(
23	* 'loader' => new Mustache_Loader_FilesystemLoader(dirname(__FILE__).'/views'),
24	* 'partials_loader' => new Mustache_Loader_FilesystemLoader(dirname(__FILE__).'/views/partials'),
25	* ));
