Creates a newMemCacheStore object, with the given memcached server addresses.
Each address is either a host name, or a host-with-port string in the form
of “host_name:port”. For example:
If no addresses are provided, but ENV['MEMCACHE_SERVERS'] is
defined, it will be used instead. Otherwise, MemCacheStore will
connect to localhost:11211 (the default memcached port).
