- * \brief CModel_Car_Drivers_Base exception class
- *
- * This class implements the exceptions for the CModel_Car_Drivers_Base class. 
- * 
- * Similarly to other exception classes, it appends a class identifer
- * string ("[CModel_Car_Drivers_Base] - ") to the error message in order to identify the
- * class that generated the exception.
- * 
- * The base class can be used to catch any exception thrown by the application
- * or also, this class can be used in order to catch only exceptions generated 
- * by CModel_Car_Drivers_Base objects.
