#initialize(config = {}, &block) ⇒ PadReader

You may pass height, width, row and col for creating a window otherwise a fullscreen window will be created. If you pass a window from caller then that window will be used. Some keys are trapped, jkhl space, pgup, pgdown, end, home, t b This is currently very minimal and was created to get me started to integrating pads into other classes such as textview.
