13 * Loads a template from a string.
14 *
15 * This loader should only be used for unit testing as it has many limitations
16 * (for instance, the include or extends tag does not make any sense for a string
17 * loader).
18 *
19 * When using this loader with a cache mechanism, you should know that a new cache
20 * key is generated each time a template content "changes" (the cache key being the
21 * source code of the template). If you don't want to see your cache grows out of
22 * control, you need to take care of clearing the old cache file by yourself.
