GraphQL interface to a list of names.. to can query by id, and can add
names. There's no dupe check, no remove/delete, not even a way to
enumerate stored values.
The trickiest part of the incrementing id for addPerson. Initially I
reused some of the HashMap in a Mutex pattern to store u32s, well u8 at
first but that doesn't cast to a juniper scalar type. I don't know why
that didn't work. The incremented value didn't seem to persist in the
hash.
