/**
 * Class to hold information about a detected or recognized face in a photo.
 * 
 * When a face is detected, the camera believes that a face is present at a given location in
 * the image, but is not sure whose face it is.  When a face is recognised, then the face is
 * both detected and identified as belonging to a known person.
