Next steps:
 * Object creation and destruciton:
   1. The !NetworkStream creates a [wiki:NetworkSocket NetworkSocket] in its constructor
   1. The !NetworkStream deletes and uninitializes the [wiki:NetworkSocket NetworkSocket] in its constructor
 * processData() function: upstream
   1. it first gets the data from the underlaying [wiki:NetworkSocket NetworkSocket].
   1. pass the data to the [wiki:ConnectionMonitor ConnectionMonitor]::processData();
   1. pass the data to the [wiki:NetworkProtocol NetworkProtocol]::removeHeader();
   1. pass the data to the [wiki:Synchronizeable Synchronizeable] object
 * processData() function: downstream
   1. get the data from the [wiki:Synchronizeable Synchronizeable] object
   1. pass the data to the [wiki:ConnectionMonitor ConnectionMonitor]::processData();
   1. pass the data to the [wiki:NetworkProtocol NetworkProtocol]::removeHeader();
   1. pass the data to the [wiki:NetworkSocket NetworkSocket] object
