Add great boy example (#48)
* Progress towards mock MainPod verification * add MockMainPod.pub_statements logic so that when originid==SELF it is replaced by self.id() * Basic op checking for mock MainPOD * More op checking * wip * feat: add great boy example * feat: put examples under cfg(test) --------- Co-authored-by: Ahmad <root@ahmadafuni.com> Co-authored-by: arnaucube <git@arnaucube.com>
