Provide own Cache for performance improvements. For example saving Session between multiple calls

// cache adapter
<?php
use NextEvent\PHPSDK\Store\StoreInterface;

class MyCache implements StoreInterface
{

 public function set($key, $value)
 {
   // your implementation
 }

 public function get($key)
 {
   // your implementation
 }

 public function clear()
 {
   // your implementation
 }
}
?>

// initialize
<?php
$my_cache = new MyCache();

// on initialize
$ne_client = new \NextEvent\PHPSDK\Client($appUrl, $credentials, $widgetHash,
$my_cache);
// or
$ne_client->setCache($my_cache);
?>
