next.jdbc.result-set
An implementation of ResultSet handling functions.
Defines the following protocols:
- ReadableColumn -- to read column values by label or index
- RowBuilder -- for materializing a row
- ResultSetBuilder -- for materializing a result set
- DatafiableRow -- for turning a row into something datafiable
Also provides the default implemenations for Executable and the default datafy/nav behavior for rows from a result set.

ReadableColumncljprotocol
Protocol for reading objects from the java.sql.ResultSet. Default implementations (for Object and nil) return the argument, and the Boolean implementation ensures a canonicalized true/false value, but it can be extended to provide custom behavior for special types.
