             Fix For: 0.7.0


NonZeroIterator of DenseDoubleVector never reaches the end.

This bug can be check by the following snippet of code.

{code:title=TestDenseDoubleVector.java|borderStyle=solid}
  @Test(timeout=100)
  public void testIterator() {
    double[] expectedRes = new double[] {38, 44, 50, 56, 0, 0, 3, 0, 0, 0};
    DoubleVector vec = new DenseDoubleVector(expectedRes);
    
    Iterator<DoubleVectorElement> itrNonZero = vec.iterateNonZero();
    while (itrNonZero.hasNext()) {
      itrNonZero.next();
    }
  }
{code}
