* Description: 

*      An interface for the CLogsNaviDecoratorWrapper. This is basically needed 

*      to hide implementation from Logs Plugin wich inherits CLogsBaseControlContainer.

*      Instead of using the singleton directly in CLogsBaseControlContainer we pass an 

*      interface object and then we dont have to add CLogsNaviDecoratorWrapper.cpp to the

*      Logs Plugin project file.

*
