Allow a Creator to define multiple families so that a creator can
e.g. specify `usd` and `usdMaya` and another USD creator can also
specify `usd` but apply different extractors like `usdMultiverse`.
There is no need to override this method if you only have the
primary family defined by the `family` property as that will always
be set.
