Error conveyance

[Aaron Bartell]

Currently the iToolkit callback function only operates on a single result parameter and doesn't also include an error parameter. Errors could result from the DB2 connection.

Would be good to add this so errors can be conveyed.

Yes, this is a design issue. We should follow the Node.js callback style -- https://nodejs.org/dist/latest-v4.x/docs/api/errors.html#errors_node_js_style_callbacks But the new error parameter is the first parameter of functions, which may break current user code. Maybe we'd better make the changes in next majoy version upgrade.
