trying to set extra options in error to send to response. #102

I want to set extra options in error response. Didn't find the exact solution anywhere.

tried passing in the body

const errors = require('restify-errors');
new errors.MethodNotAllowedError({ body: { extra: option } }, some-error-message));

what's the exact method to allow some extra options in error response?

Is there a way to set the default for all the errors and just pass the extra field parameters?

Also, I just want options in already existing error methods.
