Added a .js for Modal Popups but haven't implemented it yet.  Also added code for how the handle picking and replacing monkeys in a full barrel... but haven't implemented it until I get the Modal Popup working.
Ok.. NOW I added the .js for Modals
Messing with Modals.
Removed Modal while researching best implementation, fixed some logic issues.
