8   /* A Simple console demonstration to show how we can use a resource Bundle to list
9    Known Key pairs  */

11  /* 1: What would we use this for lanaguage converters 
12     2: Currency Converters 
13     3: Populating Option Select objects in an Html Form
14     4: Military applications for Coding of words Every time you whish to reencode a 
15  word  you might use
16        a Rescource Bundle to do this 
17     5: Scientific uses
