OK, here is the draft quartz3 node. It is incomplete.

There has been no time for testing. It is loadable in nodeeditor under MoI4.
The theory is that the Cycle Once node uses most of the same code as the Cycle Continuous node, except that when it gets to the end the first time,
the value of hz[0] is set to 0. Tic-toc Once mode has not been coded for. Cleanup has not been done.
