Provide example for car sharing

[nucknorris]

• There should be an example how to model car sharing parking spaces
• maybe create FAQ.md and add examples there

[pietercolpaert]

@nucknorris Could you create such an example that we could discuss and extend upon?

An example here: https://github.com/stijnbrysbaert/OSLO-extention/blob/master/station_status.ttl

Needs an extension of mobivoc
