Fix v0.1.0 issues identified by reviewers

[nanxstats]

• If there are references describing the methods in your package, please add these in the description field of your DESCRIPTION file in the form authors (year) doi:... authors (year) arXiv:... authors (year, ISBN:...) or if those are not available: <https:...> with no space after 'doi:', 'arXiv:', 'https:' and angle brackets for auto-linking.
  (If you want to add a title as well please put it in quotes: "Title")

• \dontrun{} should only be used if the example really cannot be executed (e.g. because of missing additional software, missing API keys, ...) by the user. That's why wrapping examples in \dontrun{} adds the comment ("# Not run:") as a warning for the user.
  Does not seem necessary.
  Please unwrap the examples if they are executable in < 5 sec, or replace \dontrun{} with \donttest{}.

  Instead of cat() rather use message()/warning() or if(verbose)cat(..) (or maybe stop()) if you really have to write text to the console (except for print, summary, interactive functions).

• You are setting options(warn=-1) in your function. This is not allowed.

• Please always make sure to reset to user's options(), working directory or par() after you changed it in examples and vignettes and demos. -> inst/doc/GraphicalMultiplicity.R, e.g.:

old <- options(scipen = 999)
...
options(old)

It looks like all identified issues are now resolved, so I'm closing this.
