deep cloning of objects (v12)

Revision 12 of this benchmark created by Oscar Campbell on

Description

Testing only DEEP cloning of objects. Minimum requirement is to pass 'everything that can be JSONed' test. To reduce the impact of the validation test, several runs are done in each test round. /ORC Had to bump this (rev. 10) to rev. 12. Cause there is a faulty one on rev. 11.
