Sudoku

This is my implementation of a Sudoku interface.
It is capable of creating and solving sudokus with basic sudoku logic.
The current logic is:

• Last possible number
• Last remaining cell

ToDo

• Implement more sudoku logic
  • Naked pairs
  • Hidden pairs
  • X-wing
  • Y-wing
  • Swordfish
• Restructure to be more readable
• Separate into multiple files
• Add support for more sudoku sizes
• Add support for multiple Boards with shared borders or subcells
• Add support for forced solutions
• Possibly rewrite the solving algorithm
