Different solve path's

[sok63]

Hello! Thanks for your work! I have tested your solver, comparing to http://www.sudokuwiki.org/sudoku.htm solver and find that you solver use more tehniques to solve some sudoku's than on the site - which mean that there are some bugs in solver.
For example this two sudoku can be solved(on sudokuwiki) without using Naked Quad:
100000700006920000009308500000090008000072000350000007000001090600009410000640800
103450000000000020400807000381070000600300000000000900000500004000002800005061000

Hey sok63,

Thanks for taking an interest! Unfortunately, I haven't worked on this project in quite some time, and I don't currently have the bandwidth to look at it. However, please feel free to submit a fix if you have time and find a solution.

As a first start, I would ensure the solver ordering you used is the same as that for sudokuwiki. The solver order is entered as a tuple when creating the SudokuSolverBuilder, as in main.py.
