BinomialBoundsN may divide 0

[ZENOTME]

From exception, BinomialBoundsN is expect to not take the 0 theta.(To prevent "divide 0" happend).

throw new SketchesArgumentException("0.0 < theta <= 1.0: " + theta);

But actually it doesn't check whether theta is 0.

Following test is fail to check this because this test will pass if any checkArgs throw exception.

  @Test
  public static void checkCheckArgs() {
    try {
      checkArgs(-1L, 1.0, 1);
      checkArgs(10L, 0.0, 1);
      checkArgs(10L, 1.01, 1);
      checkArgs(10L, 1.0, 3);
      checkArgs(10L, 1.0, 0);
      checkArgs(10L, 1.0, 4);
      fail("Expected SketchesArgumentException");
    } catch (final SketchesArgumentException e) {
      //pass
    }
  }
