New generates a new ResponseAssembler for sending responses.

ResponseAssembler manages assembling responses to go out over the network in libp2p messages.

PeerMessageHandler is an interface that can queue a response for a given peer to go out over the network If blkSize > 0, message building may block until enough memory has been freed from the queues to allocate the message.

ResponseBuilder is a limited interface for assembling responses inside a transaction, so that they are included in the same message on the protocol.

Transaction is a series of operations that should be send together in a single response.
