View commands affect what is displayed while the simulation is running.
Adds nodes to a watch-list of nodes to display when their values change, much like breakpt, but doesn't interrupt simulation.
Display every node value change (regardless of present in watch-list). nowatchall restores the state where only explicitly watched nodes are displayed on value changes.
cause displays causal information of nodes as they change value. nocause hides cause information, but silently keeps track.
tcounts displays transition counts on nodes as they change value. notcounts hides transition count information.
