Develop demo application for reading and displaying card contents

[alranel]

In order to facilitate developers to understand how to use this SDK, it would be useful to provide them with the source code of a full desktop application that reads the card DGs and displays data and photo.

An example scenario for such an app would be a hotel check-in, where people could just provide their CIE to the receptionist instead of having their paper ID photocopied. The app would even provide a quick way for sending data to the Police (which collects information about guests) through a web service.
