Fix NPE in SQL Quadstore
...
When `tx.Exec` fails and an error is returned, result is nil. Thus, `result.RowsAffected()` panics.
* Add a missing return statement in the error test.
* Add a second missing return statement just below to return the proper error message if we can't execute `RowsAffected` instead of saying that the triple doesn't exist.

Added more documentation, converted logical operations to (hopefully)
consistent 'route' metaphor, and moved all AND(iterator, iterator)
