Layout manager that places components where they are manually specified to be and sizes them to the size they are 
manually assigned to. When using the AbsoluteLayout, please use setPosition(..) and setSize(..) manually on each
component to choose where to place them. Components that have not had their position and size explicitly set will
not be visible.
