I don't think it is necessary or useful to use FieldWriter for non-complex
types.
Should we change it so that non-complex types use "set" and "setNull" directly
on the vector?
I believe this would remove some of the indirection which is making the code
harder to debug.
If we are very close to making it work with FieldWriter on non-complex types,
let's go ahead with that.
I'm just concerned we get stuck trying to fix something that isn't necessary.
