function hook_cache_flush
hook_cache_flush()
Flush all persistent and static caches.
This hook asks your module to clear all of its static caches, in order to ensure a clean environment for subsequently invoked data rebuilds.
Do NOT use this hook for rebuilding information. Only use it to flush custom caches.
Static caches using drupal_static() do not need to be reset manually. However, all other static variables that do not use drupal_static() must be manually reset.
