2 * @file network_stream.h
3 *  implementation of a network pipe. This node handles the handshake of two network nodes and exchanges informationas
4 * vial to the connection setup.
5 *
6 * the local node only writes in the localState variable. the remoteState variable will be written from the remote network node
7 * so don't write into it!
