Hi,
Just want to add my 2 cents on this pull request which was merged.

IMO It shouldn't throw error in case of umapped JSON Key. I've multiple case where server respond lot of field in JSON response and i don't want to get them all in my object, so no reason to throw an error.

At least it should be configurable, one should be able to choose to be "strict" or not on mapping.

More than that, the pull requested merged seems to have error in it, as it silently fails.

Seems due to line 150 in "antle/MTLJSONAdapter.h" where code is 
if (error != NULL) {

Should be
if (error == NULL) {

As there is no current error, it show nothing.

Thanks in advance for fixing the issue.

Regards,
