Database.Stub.Enumerator

Stub implementation of Database.Enumerator. Useful for people who can't or won't install a DBMS, so that they can try out the Enumerator interface.

Currently last last row of any fetch will have a null in its Int columns (this makes it easier to test handling of nulls and DBUnexpectedNull). See fetchIntVal.

data QueryResourceUsage

At present the only resource tuning we support is the number of rows prefetched by the FFI library. We use a record to (hopefully) make it easy to add other tuning parameters later.
