assume() starts the context for setting defaults, so assume().format(...) sets a default format
  mark(ms) starts the script step context, saying, at time ms, do the action
  then() just continues the previous mark
  head() is a custom action, not a built-in, it clears the existing column and puts a headline up.
  sketch() is a built-in, it will cause the following actor to be sketched.
  letters() is a custom object(), creating a text and modifying it.
  group(), name(), at() and format() are all built-ins, all objects support them.
  
  private Step stack2()
	{
		assume().format("largeCodeFormat");
		mark(0).head("A Program's Stack");
		then().drawStack();
		mark(22).head("The Household Progam");
		mark(26).sketch().letters("main()").group("stack").at(stackTextPosition(0));
		mark(30).sketch().letters("doChores()").group("catchAndThrow").at(stackTextPosition(1));
		mark(33).sketch().letters("takeOutTrash()").group("stack").at(stackTextPosition(2));
		mark(37).sketch().letters("putBagsInCans()").group("stack").at(stackTextPosition(3));
		mark(40).sketch().letters("putOneBagInCan()").group("stack").at(stackTextPosition(4));
		mark(44).sketch().letters("openCan()").group("catchAndThrow").at(stackTextPosition(5));
		then().sketch().letters("whoops, he forgot openCan()").named("joke").at(jokePosition());
		mark(49).fadeOut().the("joke");
	}
