Removed the addLoadPanel and removeLoadPanel methods, since they were unused and replaced by the setLoadPanelVisible method. Added step.setStepSize() to the else clause of the addStep method. Added resetProtocol() after the create protocol checkbox gets unchecked.
Added code for the beautifying and animation of the walls of the rectangle geometry
