A Begin message creates a new data stream.
A set of recognized flags that can be attached to a begin cell.

A Data message represents data sent along a stream.

An Extend2 message tells the last relay in a circuit to extend to a new hop.

A Sendme message is used to increase flow-control windows.
A Truncated message is sent to the client when the remaining hops of a circuit have gone away.
