+ * Flexible error handler, providing (_optional_) stack traces
+ * and error message responses for requests accepting text, html,
+ * or json.
+ *
+ * Options:
+ *
+ *   - `showStack`, `stack` respond with both the error message and stack trace. Defaults to `false`
+ *   - `showMessage`, `message`, respond with the exception message only. Defaults to `false`
+ *   - `dumpExceptions`, `dump`, dump exceptions to stderr (without terminating the process). Defaults to `false`
+ *
+ * Text:
+ *
+ *   By default, and when _text/plain_ is accepted a simple stack trace
+ *   or error message will be returned.
+ *
+ * JSON:
+ *
+ *   When _application/json_ is accepted, connect will respond with
+ *   an object in the form of `{ "error": error }`. 
+ *
+ * HTML:
+ *
+ *   When accepted connect will output a nice html stack trace.
+ *
+ * @param {Object} options
+ * @return {Function}
