Creates new token of the +object+ and adds it to the marking.
 Objects added to the marking are deep-cloned, so you can use them
 without fear to interfere with TCPN simulation. But have it in mind!
 If you put a large object with a lot of references in the marking,
 it will significanntly slow down simulation and increase memory usage.
