+Simple python game:Ocean treasures 
+
+ Simple game in which you have to find treasure chests lost in the 
+ bottom of the ocean. The ocean is represented by a grid of 60 columns 
+ by 15 rows and the chests can be in any one cell. To find a chest you 
+ need to drop sonar devices at given locations. 
+
+ To play, click buttons to drop sonar device. 
+ The sonar reports the distance to the treasure.
