Defines a factory that creates new ACE_Associations passively.
The <ACE_SOCK_SEQPACK_Acceptor> has its own "passive-mode" socket. This serves as a factory to create so-called "data-mode" sockets, which are what the ACE_SOCK_SEQPACK_Association encapsulates. Therefore, by inheriting from <ACE_SOCK>, <ACE_SOCK_SEQPACK_Acceptor> gets its very own socket.
