Live monitoring of directory for real-time fitting

[Paradoxdruid]

Add functionality - new GUI or enhancement - to monitor a folder and process data as it is saved in real-time.

This is a simple but perhaps useful approach:

import os, time
path_to_watch = "."
before = dict ([(f, None) for f in os.listdir (path_to_watch)])
while 1:
  time.sleep (10)
  after = dict ([(f, None) for f in os.listdir (path_to_watch)])
  added = [f for f in after if not f in before]
  removed = [f for f in before if not f in after]
  if added: print "Added: ", ", ".join (added)
  if removed: print "Removed: ", ", ".join (removed)
  before = after
