-/**
- * Cache provides a consistent interface to Caching in your application. It allows you
- * to use several different Cache engines, without coupling your application to a specific
- * implementation. It also allows you to change out cache storage or configuration without effecting
- * the rest of your application.
- *
- * You can configure Cache engines in your application's `bootstrap.php` file. A sample configuration would
- * be
- *
- * ```
- *	Cache::config('shared', array(
- *		'engine' => 'Apc',
- *		'prefix' => 'my_app_'
- *  ));
- * ```
- *
- * This would configure an APC cache engine to the 'shared' alias. You could then read and write
- * to that cache alias by using it for the `$config` parameter in the various Cache methods. In
- * general all Cache operations are supported by all cache engines. However, Cache::increment() and
- * Cache::decrement() are not supported by File caching.

- * `Cache::config('my_config', array('engine' => 'File', 'path' => TMP));`
- *
- * If you need to modify a configuration temporarily, use Cache::set().
- * To get the settings for a configuration:
- *
- * `Cache::config('default');`
- *
- * There are 5 built-in caching engines:
- *
- * - `FileEngine` - Uses simple files to store content. Poor performance, but good for
- *    storing large objects, or things that are not IO sensitive.
- * - `ApcEngine` - Uses the APC object cache, one of the fastest caching engines.
- * - `MemcacheEngine` - Uses the PECL::Memcache extension and Memcached for storage.
- *   Fast reads/writes, and benefits from memcache being distributed.
- * - `XcacheEngine` - Uses the Xcache extension, an alternative to APC.
- * - `WincacheEngine` - Uses Windows Cache Extension for PHP. Supports wincache 1.1.0 and higher.
- *
- * The following keys are used in core cache engines:
- *
- * - `duration` Specify how long items in this cache configuration last.
- * - `groups` List of groups or 'tags' associated to every key stored in this config.
- *    handy for deleting a complete group from cache.
- * - `prefix` Prefix appended to all entries. Good for when you need to share a keyspace
- *    with either another cache config or another application.
- * - `probability` Probability of hitting a cache gc cleanup. Setting to 0 will disable
- *    cache::gc from ever being called automatically.
- * - `servers' Used by memcache. Give the address of the memcached servers to use.
- * - `compress` Used by memcache. Enables memcache's compressed format.
- * - `serialize` Used by FileCache. Should cache objects be serialized first.
- * - `path` Used by FileCache. Path to where cachefiles should be saved.
- * - `lock` Used by FileCache. Should files be locked before writing to them?
- * - `user` Used by Xcache. Username for XCache
- * - `password` Used by Xcache/Redis. Password for XCache/Redis
- *
