A very simplistic file cache that uses the ArrayAcces interface

1. Include SimpleCache.php in your project

require_once 'SimpleCache\SimpleCache.php';

2. Instantiate the SimpleCache class and provide a cache directory

$cache = new \SimpleCache\SimpleCache('./tmp');

3. Use the $cache object like any array. Index names will be created as files. When you run the script again the index will still have the value you assigned it.
