> collect has the following methods:
> Collection collect(Collection inputCollection, final Transformer transformer)
> Collection collect(Collection inputCollection, final Transformer transformer, final Collection outputCollection)
> The first creates an ArrayList(), where the second takes an outputCollection and, for convenience, returns it.
> Select (and selectReject) currently the following methods:
> Collection select(Collection inputCollection, Predicate predicate)
> void select(Collection inputCollection, Predicate predicate, Collection outputCollection)
> I propose changing the bottom method to return the passed in outputCollection.  It would simplify calling code.
