-    NewJob should occur per path (or potentially all paths in import_dir), then you know #files for new non-scan jobs
-        if we make jobs be minimum, then ditch pass, and just use wait_for...

-    Jobs should be:
-        scan for files in DIR -> returns knows num_files in DIR
-        get thumbs for files (in DIR)
-            TODO: The 2 above lines are in GenerateFileData AND work on all import_dir paths at once, need to split this up (so our current setup would be 5 jobs (1 fail) on borric):
-                Job-1: Scan images_to_process -> success (num_files_1)
-                Job-2: Scan C: -> fail (report back to web)
-                Job-3: scan new_image_dir -> success (num_files_2)
-                Job-4 (wait on 1): Gen thumbs images_to_process (on num_files_1)
-                Job-5 (wait on 3): Gen thumbs new_image_dir (on num_files_2)
-                (worst case if a job waited on job-2, and 2 failed, then auto-fail it.)

-        process AI (<1 person>) for files (in DIR), e.g.
-            Job-7: scan 'cam' in images_to_process (num_files_1)
-            Job-8 (wait for 7): scan 'cam' in new_image_dir (num_files_2)
-            Job-9 scan 'dad' in images_to_process (num_files_1)
-            Job-10 (wait fo 9)scan 'dad' in new_image_dir (num_files_2)
-            etc.  
-                this way we ditch passes

     num jobs active, num jobs completed, lets bin them from the pa_job_manager table -> calculate them everytime (simple select count(1) from job where pa_job_state == "Completed")
     FE does not really care what 'state' the job engine is in anyway, so maybe we bin that table, make it a local class to pa_job_manager?
