#33 add_event_detect edge as argument to callback function

When using add_event_detect function to detect pin state changes, it would be nice if edge comes as argument to callback function like this:

def my_cb_function(gpio, edge):
  if edge == GPIO.FALLING:
    print "Falling edge"

GPIO.add_event_detect(pin_number, GPIO.BOTH, callback=my_cb_function)

Now I have to check pin state in my callback function.

Maybe the argument passing could be even more general. For instance if you want the callback function to do something useful (rather than just print something) then it would be nice to be able to pass a pointer to some object to be updated (otherwise only way seems to be to have globals). You could do worse than the threading.Tread system i.e.

GPIO.add_event_detect(pin, GPIO.BOTH, my_func, args=(a, b ,c))
