[TASK] Internal design of Lights Out game as stubbed source code

[jody]

Identify the method-signature level design of the LightsOutGame class.
Consider guidance given in parent issue #88

Create method stubs in LightsOutGame.java

[jody]

Consider representing the board as a matrix of boolean values, where true means "on" and false means "off".

Thoughts on potential public and nested inner classes for the LightsOutGame.

public class LightsOutGame {
    public LightsOutGame();
    public LightsOutGame(InputStream in);
    public LightsOutGame(InputStream in, LightsOutBoard board);
    public String getName();
    public Optional play();

    static class LightsOutBoard {
        public LightsOutBoard(int numRows, int numColumns);
        public LightsOutBoard(LightsOutBoard other); // A copy constructor.
        public boolean toggle(int row, int column); // Toggles specified cell and its neighbors.
        public String display(); // ASCII board display with annotations.
        boolean getCell(int row, int column);
        void setCell(int row, int column, boolean value);
    }
}
