Mine Checker: Web based minesweeper game

This class implements a Web based version of the classic minesweeper game.

The class generates the game area layout of mines that is stored in bidimensional array. That array should be stored in a session variable so it can be reloaded after each game play turn.

The class can process each game play turn given the coordinates of next position of the board that the player wants to move.

At any moment the class can automatically check if the player has won by determining if all positions without mines were discovered.
