is an abstract base class for type converters from the SQL type system.

Implementing classes have to provide a dict simpleMap mapping sql type strings to target types, and a method mapComplex that receives a type and a length (both strings, derived from SQL array types) and either returns None (no matching type) or the target type.

Implementing classes should also provide a typeSystem attribute giving a short name of the type system they convert to.
