Allow mapping of data to a ViewModel

[csharpfritz]

Introduce configuration to allow mapping from the datasource to a ViewModel, and mapping from the ViewModel to the datasource

Using Automapper may be the preferred technique here

Very good idea.
Should we rather refer to them as Data Transfer Objects (DTOs), and not ViewModels?

[csharpfritz]

I think you're right @ChristianWeyer - in APIs they're DTOs since there is no UI
