+
+/**
+ * Phonebook 2 smart destruction indicator.
+ * Responsible for reseting the destruction indicator pointer in case
+ * the destruction does not happen. This class is meant to be used
+ * in classes that launch waiting dialogs. If application is killed
+ * during the dialog the dialog code will return and run the code of the
+ * deleted object. In that case the deleted object has to perform some checks
+ * to find out if it is deleted. This class is used in that process to
+ * help to perform that task safely.
