 This package tunnels the Corpus Query interface (CQi) protocol through
-Socket.IO (SIO) by wrapping each CQi function in a seperate SIO event.
+Socket.IO (SIO) by tunneling CQi API calls through an event called "exec".
-
-This module only handles the SIO connect/disconnect, which handles the setup
-and teardown of necessary ressources for later use. Each CQi function has a
-corresponding SIO event. The event handlers are spread across the different
-modules within this package.
 
 Basic concept:

+2. The client emits the "init" event and provides a corpus id for the corpus

      1.1 The analysis session counter of the corpus is incremented.
      1.2 A CQiClient and a (Mutex) Lock belonging to it is created.
      1.3 Wait until the CQP server is running.
