-/**
-* Basis for the implementation of the database.
-*
-* Constructs instances of database subclasses CCbsDbImpSettings,
-* CCbsDbImpTopicCollection, CCbsDbTopicList and CCbsDbTopicMessages.
-* On initialization determines whether datafiles already exist.
-* If all of them are present and valid, no special action is taken.
-*
-* If some or all datafiles are missing or corrupt, all datafiles
-* are deleted and new files created.
-* Factory default settings, if available, are then loaded from
-* Shared Data and stored in server datafiles. This is done by
-* database subinstances.
