/**
 * APC API Wrapper for Zend Data Cache
 *
 * This script will define APC-like wrapper functions for use with the Zend 
 * Data Cache API. This will allow APC users to replace APC with Zend Data 
 * Cache without changing their code.
 * 
 * In order to use, simply include this file at the top of any request that
 * uses any APC API function. It is also possible to set auto_prepend_file in
 * php.ini to point to this file - this will make sure the file is 
 * automatically included in all PHP requests.
 *  
 * Including this script should have no side effects if APC is loaded, and will
 * define the wrapper functions only if APC is not loaded and Zend Data Cache 
 * is.
