Graphic data entry

[Doom4535]

It would be nice to have some sort of a GUI to allow the user to input the puzzle state to solve for (and desired ending state). See: https://github.com/raysan5/raylib

I got a crude version of a GUI working, but I'm not sure how to connect it to GitHub so it works between computers and when downloaded. We'll need to know how data will be represented the program in order to finish setting this up.

edit:
I've been messing with it more, I think we should make it so that

• the user populates the board, and clicks go,
• the window will close,
• and then it will begin the processing we've already started coding
• and then it'll output a file with a list of moves, or some representation of the path

because the gui runs on a loop with a bunch of loops inside it, and it'd be easier to just use it once and be done with it, rather than doing everything in the gui and processing the board at the same time.

the advantage of the gui though is that the buttons can be used for data entry instead of the keyboard, so no need for input validation, except to make sure the board is solvable.

Ok, I like it; it should also improve performance because we won't be constantly redrawing the board.
