+The user sometimes needs to keep in the study only some objects that

+
+The feature is especially useful when the user designs the whole model 
+through the GUI and wants to generate simplified "clean" Python dump only 
+at the end of the model construction with no "useless" objects in the 
+%GEOM module.
