module for detecting English ordinal numbers

 Lingua::EN::Number::IsOrdinal will tell you if a number, either in words or
 as digits, is a cardinal or ordinal number
 <http://www.ego4u.com/en/cram-up/vocabulary/numbers/ordinal>.
 .
 This is useful if you e.g. want to distinguish these types of numbers found
 with Lingua::EN::FindNumber and take different actions.
