An improvement from my other sudoku project on @ProdigyZeta7 using my 2D Array framework for application. Also been thinking of transferring my projects from there over to this account... Also changed from my previous project is the ability to export and import sudoku puzzles (partly in CSV format), and choosing whether to solve an ambiguous puzzle through random simulation. Error checking might still need to be added, though at this point it can solve a puzzle in reasonable time. [E]xport and [I]mport are some options. Or you could go inside and click the scripts which are right there.
