C++ : This mini project builds off lab 1. This is the knight's tour.

For this project, take the code from your last project.

The program will do the following:

Ask the user for a starting position.

Places the knight in that starting position and calculates all legal moves. Each move will be numbered.

The user will choose a number and the knight will move to that space and recalculate the number of legal moves.

With each move you will also give the user the option to either start a new game or exit the program.

The program ends when the user wishes.
