TableViewPlayground: Using View-Based NSTableView and NSOutlineView

The TableViewPlayground demonstrates using the view based NSTableView and NSOutlineView. Four different samples are shown. First, a HUD window with an NSTableView that completely uses bindings to display sample windows to create. Second, a basic View Based TableView implementation is shown using delegate and dataSource methods. Third, a complex TableView example based on the AnimatedTableView demo application. Finally, a complex NSOutlineView demo that mixes bindings and a dataSource to get the job done.
