Single page viewer example in the same vein as SimpleViewer. Resolves #8951

I think there is someone already started working on this issue, so IMO it is unethical to submit a PR. I would suggest to try some other issues also(there are quite a lot with good-begineer-bug label). Please confirm(or ask to assign the issue) in future, that someone is not working on the issue before submitting a PR. Rest I am leaving on the project members.

@timvandermeij can you please have a look on this?

[timvandermeij]

Yes, next time please indicate on the issue that you're (planning to be) working on the ticket. This is done to avoid double work, because now two people worked on the exact same issue.

Code-wise this looks good at first glance, but it still needs a more in-depth review with testing.

Closing since the fix is already merged in #8990. Nevertheless, thank you for your looking into this!
