### var tcp = new Tcp()
`libp2p-tcp` accepts TCP addresses both IPFS and non IPFS encapsulated addresses, i.e:
Creates a new TCP object. This does nothing on its own, but provides access to
`dial` and `createListener`.
`/ip4/127.0.0.1/tcp/4001`
`/ip4/127.0.0.1/tcp/4001/ipfs/QmHash`
### tcp.createListener(multiaddrs, handler, ready)
Both for dialing and listening.
Creates TCP servers that listen on the addresses described in the array
`multiaddrs`. Each connection will call `handler` with a connection stream.
`ready` is called once all servers are listening.
### tcp.dial(multiaddr, options={})
Connects to the multiaddress `multiaddr` using TCP, returning the socket stream.
If `options.ready` is set to a function, it is called when a connection is
established.
### tcp.close(callback)
Closes all the listening TCP servers, calling `callback` once all of them have
been shut down.
