Creates and generates a 2 dimensional array with various path generation functions.

/**
 * Receives the 8 neighbors around a cell to determine the index of the sprite to display for Nichathan Gaming's mapRenderer.

 * Neighbors are tracked by their value:
 * 1 2 3
 * 4 * 5
 * 6 7 8
 * 
 * count cardinal directions first then diagonals if they are not next to an unpathed value.
 * @param {number[]} mismatchedNeighbors 
 * @param {number[]} matchingNeighbors 
 * @returns {[number, number]} The index of the sprite to display.
