==CFrame==
The code for this class is provided. You must understand and use it to develop your core classes.
CFrame class is responsible to create a frame or structure in which all user interface classes contain themselves in. It can draw a border around it self or be border-less.
CFrame also, before displaying itself on the screen, will save the area it is about to cover, so it can redisplay them to hide itself.
CFrame is base of all objects in our user interface system.
