// Class : CConnectionRepository
// Description : This class implements the C++ side of the
// ConnectionRepository object. In particular, it
// manages the connection to the server once it has been
// opened (but does not open it directly). It manages
// reading and writing datagrams on the connection and
// monitoring for unexpected disconnects as well as
// handling intentional disconnects.
//
// Certain server messages, like field updates, are
// handled entirely within the C++ layer, while server
// messages that are not understood by the C++ layer are
// returned up to the Python layer for processing.
