User Feedback: provide vCard Examples

[wsdwl]

On 6th of January we received the following Feedback:

You need to provide vCard examples. You do provide examples for Calendar entries but these are not the same. I found a good general discussion, but it lacks the specificity required for programming.

Suggestion would be to add here a page like this one about the Data-Model and this one about a simple event -> vCard.

@ronaldtse : Do you think, that's something your guys can provide?

@wsdwl sorry forgot about this, will do a page on this.
