Visage Face Recognition giving null pointers
User Story/Description
The visage face recognition seems to be giving null pointers when finding a face which in turn crashes the json library.
Definition of Done
When no more null pointers are given and the webserver and node are stable (doesn't crash), this might include fixing other issues as well but hopefully not.
How
Best way is probably to start of by printing in the visage_server.cpp file, it seems to find a face but it then crashes (perhaps when trying to find the similarity?).
