Add automatic user feedback reporting

[vemonet]

Implement a proper way to get feedback from user, ideally triggered after the user used the platform enough to comment?

Look into literature, about what needs to be assessed

It could be interesting to get in contact with the developer of RDFExplorer, he added a survey to get feedback from the users on their experience. Will be a good opportunity to discuss what makes good user experience in graph exploration with a PhD working on the same issues
