NOTES:

!!!!
This program will run on its own or with the driver file named LeeShowGridLayout
The reason for this program is to help with learning Objects. The GUI based file is additonal and optional to use to help you see 
that file only calls the setter methods from object instantiation needs it must be in the same location as this file
