implementation of getNearSolution

Good library, I was using it to generate a map in MTA:SA but I didn't know how to obtain the solution of this map, I think this could help the library. It will return the closest route to the maze.

Hi, thanks for the PR! There's a couple things I'd like to point out:

• This doesn't work on mazes with more than two dimensions
• This understands simple representation coordinates, not actual maze coordinates (i.e. {1, 1} should be the cell in the top left corner, not a "wall")
• This doesn't validify user input
• It would be nice if the return value was a list of directions to move in rather than a list of coordinates

Since you're implementing this function as a method of the Maze class, it'd be more efficient to use the internal Cell objects directly instead of first converting to the simple representation. By using the internal Cell objects, you'll be able to easily query all connected cells in a dimension-agnostic way, which fixes the first two issues. Additionally, the Maze class has a few methods you might find useful for validifying user input.
