  So -- where are we?

  NA to -1 switch not made.
  edges now has a drop.root argument (default = FALSE) that
should do this.

> 5. make the naming-convention changes as recommended

  NOT DONE.  Volunteers?  Francois wanted some plurals to
be kept ...

   NOT DONE. Volunteers?

  Could add as list() if we can agree on names for the slots,
how many.

  PS: if someone wants to take a look at the "hard way" simulator
code in section 9 of the vignette and suggest ways that this could
be done more easily (possibly by adding convenience functions and/or
accessors that do the hard work), please feel free ...
