CGTopic means: Configuration Group Topic.
This object encapsulates a configuration group with topic information.
Since the topics gui conftrol uses its own data model, there is
also code here to convert from the data model to CGTopic object (the constructor)
and vice versa (setDataToRow method - used when loading the last session...)
