*
* Compiled templates are cached. If you put ?flush=1 on your URL, it will force the template to be recompiled. This
* is a hack; the system should really detect when a page needs re-fetching.
*
* Works with the global $_TEMPLATE_MANIFEST which is compiled by {@link ManifestBuilder->getTemplateManifest()}.
* This associative array lists all template filepaths by "identifier", meaning the name
* of the template without its path or extension.
*
* Example:
* <code>
* array(
* 'LeftAndMain' =>
* array (
* 'main' => '/my/system/path/cms/templates/LeftAndMain.ss',
* ),
* 'CMSMain_left' =>
* array (
* 'Includes' => '/my/system/path/cms/templates/Includes/CMSMain_left.ss',
* ),
* 'Page' =>
* array (
* 'themes' =>
* array (
* 'blackcandy' =>
* array (
* 'Layout' => '/my/system/path/themes/blackcandy/templates/Layout/Page.ss',
* 'main' => '/my/system/path/themes/blackcandy/templates/Page.ss',
* ),
* 'blue' =>
* array (
* 'Layout' => '/my/system/path/themes/mysite/templates/Layout/Page.ss',
* 'main' => '/my/system/path/themes/mysite/templates/Page.ss',
* ),
* ),
* ),
* // ...
* )
* </code>
*
* @todo Fix the broken caching.
