Overview

TILE CLASS. This class represents each of the pictures in the game window. Each tile is created with the initialize function that accepts a Gosu image for the main picture (img), x- and y-coordinates, an image to display when the tile is face down (img2), and id string, and a completion image that is displayed when the tile is matched (chkImg). The draw function renders the tile to the game window. This class contains various utility functions for tiles.
