The object of the game is to sink the ship.  There will be one ship       
on the grid.  The player will choose horizontal and vertical coordinates  
and the game will calculate whether those coordinates were a hit or a     
miss.  An "X" will mark a hit and "*" a miss.  The difficulty levels      
will be set as follows;                                                   
                                                                          
 - Easy will be a grid of 10 x 10                                         
 - Normal will be a grid of 15 x 15                                       
 - Hard will be a grid of 20 x 20                                         
                                                                          
You will have 15, 20, and 25 attempts, respectively, to sink the ship.    
If you do not, the ship will escape and you lose.
