ComparatorUtils.transformedComparator wrongly typed (generics)
--------------------------------------------------------------

                 Key: COLLECTIONS-372
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-372
             Project: Commons Collections
          Issue Type: Bug
          Components: Comparator
    Affects Versions: 4.x
         Environment: n/a
            Reporter: HaveNone
            Priority: Minor


ComparatorUtils.transformedComparator is currently typed as follows :

{{public static <I,O> Comparator<O> transformedComparator(Comparator<I> comparator, Transformer<I, O> transformer)}}

It should be typed as follows so that is can be used without removing generics typing:
{{public static <I,O> Comparator<I> transformedComparator(Comparator<O> comparator, Transformer<I, O> transformer)}}

Here is a unit test for it : 
Transformer<Integer, String> itosTransformer = TransformerUtils.stringValueTransformer();
		Comparator<Integer> c = new Comparator<Integer>() {
			
			@Override
			public int compare(Integer o1, Integer o2) {
				return o1.compareTo(o2);
			}
		};
		Comparator<String> stringComparator = ComparatorUtils.transformedComparator(c, itosTransformer);
		
		stringComparator.compare("string1", "string2");
