46f987ca51 Make graph.Delta zero state invalid for use
Previously, an incorrectly initialised Delta (omission of Action) would
result in an Add operation. Make that detectable and return an error.

This change makes tree description completely open to mechanical

b1a70d99aa Simplify Nexter interface
This change allows a Nexter to be used in the same manner as a scanner
using a for graph.Next(it) {} construction.

It is important that graph.Next(it) and any associated it.Result() calls
operate on the same iterator.

1606e98d9f Rename Check-ish -> Contains-ish
Contains[*] indicates what the check is for.

[*] I considered Has/Have, but settled on Contains to avoid confusion
with the HasA iterator.

d6f94be514 Base nexting on interface satisfaction
This is done unsubtlely at the moment and there is plenty of room for
optimisation of assertion location to prevent repeated reasserting as is
