Method that add a Object to a Collection if it was not null

           Summary: Method that add a Object to a Collection if it was not
                    null
           Product: Commons
           Version: 3.2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Collections

It would be a new static method to CollectionUtils class. It would retur 
boolean because add() method from Collection returns a boolean. It would had 
only a line:

public static boolean addNotNull(Collection c, Object o) {
   return (o != null)? c.add(o): false;
}

Of course if c was null, it will throw a NullPointerException. 
Aparently it is possible use a PredicatedCollection with NotNullPredicate. But 
it will trhow a IllegalArgumentException if o was null. It is not interesting.
