-    At the very core of SleekXMPP there is a need to track various 
-    library configuration settings, XML stream features, and the 
-    network connection status. The state manager is responsible for 
-    tracking this information in a thread-safe manner.
-
-    State 'variables' store the current state of these items as simple 
-    string values or booleans. Changing those values must be done
-    according to transitions defined when creating the state variable.
-
-    If a state variable is given a value that is not allowed according
-    to the transition definitions, a StateError is raised. When a
-    valid value is assigned an event is raised named:
-    
-    _state_changed_nameofthestatevariable
-    
-    The event carries a dictionary containing the previous and the new
-    state values.
