  /**
   * This operator takes Maps, whose values are numbers, as input tuples.&nbsp;
   * It then performs a numeric comparison on the values corresponding to one of the keys in the input tuple maps.&nbsp;
   * All tuples processed by the operator before the first successful comparison are not output by the operator,
   * all tuples processed by the operator after and including a successful comparison are output by the operator.
   *
   * <p>
   * A compare metric is done on input tuple based on the property "key",
   * "value", and "cmp" type. All tuples are emitted (inclusive) once a match is made.
   * The comparison is done by getting double value from the Number.
