NSUDS TODO
==========
- Maintain a high score table, with an option to display them in main menu
   - Global with name, date, difficulty and score stored
- In help system:
   - Use a menu for help topics, each of which launches the relevant scroller.
   - Maybe add setting to enable smooth scrolling (perhaps w/ getopt too?)
   - Expand help system with useful help, such as how to actually play sudoku.
- General
   - Fix all instances of $grep -E 'TODO|FIXME' src/*.[ch]

LONG-TERM (probably never to be implemented)
- Replace solve function in src/gen.c
- Also implement Sudoku X and Jigsaw
- Port to windows (extremely low priority)
