- Set up swapable Views for a Small and Large map.
- Created a "Controls" Window at the top of the TUI.
- Added better documentation for how Views work.
- Implemented View as an easy way to use the existing Screen and Window APIs for rendering Cells that don't fit within a Window. Basically, a user renders the oversized Cell content to a View, then renders a part of that View to a Window.
- Created the `view.zig` example.
