/**
* Class to handle loading and saving of data
*
* You must write 4 methods
*
* loadMineField - loads mine field definition
*
* saveMineField - saves minefield
*
* Here the only concern is loading/saving a mine field definition file where -1
* denotes a mine, and any non-negative number is safe.
*
* saveGame - saves the entire game state
*
* loadGame - loads the game state
*
* For a game we need both the mines and the exposed array data. Unfortunately
* the given MineField class (which you cannot change) does not provide a way to
* set that.
*
* Take a look at documentation for MineFieldIO and see if you can think of a
* way to use that shell class to help you.
