  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.
