 * See if it is really worthwhile to not check indeces in QDataSet.
 * This demonstrated that:
 * 1. the performance impact is trivial (<0.2 percent)
 * 2. a Java loop is about 1700 times faster than Jython (12.340 / 0.007) see /home/jbf/ct/autoplot/users/2016/ivar/20160902/rangeCheckPerformance.jy
