+* Description: 
+*     Stores and handles text labels for note dialogs. Each note dialog
+*     can have two different labels, one singular and one plural labels.
+*     For example:-
+*        "You have 1 new message" is the singular label and
+*        "You have 2 new messages" is the plural label.
+*     This class supports the ability to change number inside the label, e.g.:-
+*        "You have 100 new messages" is also supported.
