This is a PageFrame class that is extremely easy to design (
exactly the way you design a normal pageframe) plus it makes these 3 enhancments:
1. allows tabs to be positioned on any border of the frame.
2. allows the tabs visiblity to be toggled while its page remains (Now Easier!)
3. avoids moving a row of tabs to the bottom row when clicked
