The APC cache adapter is meant to be used through the `Cache` interface,
which abstracts away key generation, adapter instantiation and filter
implementation.

A simple configuration of this adapter can be accomplished in `config/bootstrap/cache.php`
as follows:

{{{
Cache::config(array(
    'cache-config-name' => array('adapter' => 'Apc')
));
}}}

This APC adapter provides basic support for `write`, `read`, `delete`
and `clear` cache functionality, as well as allowing the first four
methods to be filtered as per the Lithium filtering system. Additionally,
This adapter defines several methods that are _not_ implemented in other
adapters, and are thus non-portable - see the documentation for `Cache`
as to how these methods should be accessed.

This adapter supports multi-key `write`, `read` and `delete` operations.
