'cancel_var' is not defined in start_postprocess()

Error post-processing video;

Traceback (most recent call last):
  File "EcoAssist/EcoAssist_GUI.py", line 561, in start_postprocess
    if vid_json and not cancel_var:
NameError: name 'cancel_var' is not defined

Seems like cancel_var is being checked there before initialization (which only happens in process() ).

Adding global cancel_var; cancel_var = False to start_postprocess() might resolve this?

@gimmw Thanks for catching this! It is still a teething problem from adding the simple mode window. Fixed it like you suggested
