+=====Session sharing======
+Client logon with (patientid, template) tupple.\\
+Server makes lookup in active sessions for tupples matching the one supplied by the client.\\
+If none matches, a new session is created and 'returned' to the client.\\
+If a match exists, the client is queried if it want to take over the session.\\
+The session state is to be stored with the session (open, closed_no_commit) so the client must actively notify the server when a session is closed without commit.\\
+If a client is about to take over an active (not closed_no_committed) a warning should be issued, about possible race conditions happening.
