Method testOrder

src/test/java/com/rtg/util/TestUtils.java:302–318

Test the ordering of a set of objects. They should be ordered strictly monotonicly in the array. Also checks consistency of equals and hashCode with the ordering. This is the generic version. @param ator a comparator to use when doing test. @param compare an array of objects which should be in stric
