 \class CaService.
 \brief This class operates on data, anable creating and inserting new entry
 to DB, removing entry from DB, update entry or get entry from DB, executeC
 command on entry and create notifier to notify client about changes onto DB.

 CaService class uses singleton design pattern, so that it contains static
 method called instance() to get instance of a class.

 \code
 QSharedPointer<CaService> service = CaService::instance();
 \endcode

 For every operations on data is used always one instantiation of a class.
 Below are examples how to create data and work on those ones.
