Setting: wrapErrors

wrapErrors [yes,no] is a boolean setting and can be defined as CLI argument, conversion comment or method comment. This setting is inheritable.

Enable wrapErrors to instruct goverter to wrap errors returned by extend methods. Wrapped errors will contain troubleshooting information like the target struct's field name related to this error.
