push

Pushes other iterator onto this.

All calls performed on this are forwarded to other. If other returns DONE, it is popped again and calls are handled by this again.

This function is mainly used by objects implementing the iterator next function to recurse into substructures.

When resync is called on this, other will automatically be popped.

MT safe.

Parameters:

this	The Iterator to use
other	The Iterator to push
