This class uses the Memcached as the cache engine.
The constructor expects an array of servers. Each server is an item in the array with the following format:
$servers = [
'localhost:11211',
]
$cache = new \ByJG\Cache\Psr16\MemcachedEngine($servers)
$cachePool = \ByJG\Cache\Factory::createMemcachedPool($servers)
or
$cachePool = new \ByJG\Cache\Psr6\CachePool(new \ByJG\Cache\Psr16\MemcachedEngine($servers));
