Add some more documentation / example apps

[fmannhardt]

There are quite some non-trivial features that could be better documented with examples. For example, the Shiny integration to build Process Mining dashboards , custom layout, etc.

@JesseVent I saw the dashboards you build over here:
https://jessevent.shinyapps.io/loan-process/
Would you be interested in contributing a brief vignette to show how to build something like this?

[JesseVent]

Yeah would be happy too, I’ll start pulling something together
