This is a C# console app that solves Sudoku Puzzles

This application will read in a text file which represents a Sudoku puzzle that has the following format and print the solution to the console.

XXX15XX7X
1X6XXX82X
3XX86XX4X
9XX4XX567
XX47X83XX
732XX6XX4
X4XX81XX9
X17XXX2X8
X5XX37XXX

Where an X represents an empty box.

When run without any arguments the app will use the "defaultFileName" app setting in the config gile as the source file, which is currently set to "puzzle.txt".

The app can also be run with n number of file names to solve.

When given the -p flag the app will run in Project Euler Mode.

For reference: https://projecteuler.net/problem=96

The second argument will need to be the name of a file which has the same format as: https://projecteuler.net/project/resources/p096_sudoku.txt

The app will then print to the console the solution to each puzzle in the file and whether the solution is valid.
