  CaService class uses singleton design pattern, so that it contains static
  method called instance() to get instance of a class.
 
+ References to CaService instance are counted. When the number of references
+ drops to zero the instance is deleted to save memory.
+ CaNotifier class contains a member referencing to the CaService instance so
+ it is not deleted unless all CaNotifier instances are deleted (and there are
+ no variables referencing CaService).

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