Update Homework Week 15

Row 151:
	DiceArrayWriter writer1 = new DiceArrayWriter(25, sharedArray); //throw one Dice 25 times    	

Line 172:
	DiceArrayWriter writer2 = new DiceArrayWriter(i,sharedArray,3); //throw 3 Dice 5 times   

1. I only see 1 constructor.  Here we are using 2 constructor?
2. Please provide more documentation, both at the Class level and at the Method level.
