This document contains the code for a Settings class that allows the user to configure the number of rows and columns in a maze game. The class contains radio buttons and sliders to set the row and column values, which are then passed to the Maze class when the user clicks the Ok button. It implements initialization methods, event handlers, and looks up the default look and feel for the graphical interface.
