> I think we should "invert" the FieldSelector API, with a "push" API
> whereby FieldsReader invokes this API once per field in the document
> being visited.
> Implementations of the API can then do arbitrary things like save away
> the field's size, load the field, clone the IndexInput for later lazy
> loading, etc.
> This very thin API would be a mirror image of the very thin index time
> API we now have (IndexableField) and, importantly, it would have no
> dependence on our "user space" Document/Field/FieldType impl, so apps
> are free to do something totally custom.
> After we have this, we should build the "sugar" API that rebuilds a
> Document instance (ie IR.document(int docID)) on top of this new thin
> API. This'll also be a good test that the API is sufficient.
