--------------------------------------------

             Summary: Create new method in CollectionUtils to return first element if not null
                 Key: COLLECTIONS-742
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-742
             Project: Commons Collections
          Issue Type: New Feature
          Components: Collection
    Affects Versions: 4.4
            Reporter: Wesllhey Holanda


When we try to get the first element into collection, we have to lead with null point exception. So with this method, when the collection is null or empty, the method will return null, and when not, the method will return the first element.

In this way, the user don't need to write nothing to lead with null point exception.
