Detailed Description
ERXComparatorSelector allows you to pass an arbitrary Comparator instance as an NSSelector into EOSortOrdering for use with an in-memory sort. Note that this WILL NOT work for sorting directly in the database. This exploits the fact that EOSortOrdering calls selector.invoke(left, right) when you pass it an arbitrary selector to use.
Example: ERXArrayUtilities.sortedArraySortedWithKey(array, "someKey", new ERXComparatorSelector(Collator.getInstance()))
