FixedSumIterator

```
public class FixedSumIterator
extends java.lang.Object
```
Generates int[] arrays such that the sum of (k+1) * array[k] over the elements of array are equal to a given value. For example, for a target sum of 3 (as given via setSum), this iterator generates {0,0,1}, {1,1,0}, and {3,0,0} before expiring. For each case in this example, the indicated sum [respectively (0*1 + 0*2 + 1*3), (1*1 + 1*2 + 0*3), (3*1 + 0*2 + 0*3)] the indicated sum is equal to 3. Number of elements in return array is set at construction.
