## DB	
        should FPL really be EPL?

        FILE -> add, has_unidentified_face 
            ?has_face?, 

        AI_SCAN:
            id
            date of scan
            version of code?
            settings used
        AI_SCAN_FILE_LINK
            id to link to  AI_scan
            refimg used/found

### BACKEND
    *** Need to use thread-safe sessions per Thread, half-assed version did not work

    * ProcessFilesInDir (should take a path, and do the first for loop so that no one sees the recursive func)
    * Handle file deletions from file system (remove dangling DIR/FILE combos) -- also when moving to storage_dir, need to reset DIR, but keep FILE data

    Future:
        Admin
            -> reset face_flag

        AI
            -> rescan <dir> for <person> --> can do this on new image only
            (optimised to only scan has_unidentified_face)... BUT if you change
            thresholds on AI, or we get a new/better one some day, then it can
            all images with faces, or if we 'reset face_flag' rescan all images

### UI

### AI
	* store reference images (UI allows this now)
	* check images
    * allow for threshold/settings to be tweaked from the GUI
        - it would be good to then say, just run the scanner against this image or maybe this DIR, to see how it IDs ppl
    When AI kicks in, it processes per person per DIR, only compares to an image if it has_unidentified_face


### SORTER
	* date stuff
	* exif processing?
		* location stuff - test a new photo from my camera out
        -- image is in dir, need to look at exifread output
