Access to Services - A serviceLocator() method is provided to enable the derived tools to
locate the services necessary to perform their jobs. Since concrete Tools are instantiated by the
ToolSvc upon request, all Services created by the framework prior to the creation of a tool are
available. In addition access to the message service is provided via the msgSvc() method. Both
pointers are retrieved from the parent of the tool.
