Class Auth_OpenID_MemcachedStore
This is a memcached-based store for OpenID associations and
nonces.
As memcache has limit of 250 chars for key length,
server_url, handle and salt are hashed with sha1().
Most of the methods of this class are implementation details.
People wishing to just use this store need only pay attention to
the constructor.
