The only reason Keys has a template is so that it can hold a UniqueKeys
array and provide the key for each group. If that is not needed and you
want to implement a library function that takes a keys object, you can
now grab the Keys superclass KeysBase. KeysBase is not templated, so you
can pass it to a standard method in a library.
