Below is the start and stop observer code.   Can you advise on our usage
of observers?

	# set up the launch dialog handlers (helper method called from launchApp method)
	def __setUpLaunchDialogHandlers(self, maxWaitTime=200):	
		region = Screen() # get reference to OS Window
		region.onAppear( self.getAppImgPath() + "eulaDialog.png", self.__eulaDialogFound )
		region.onAppear( self.getAppImgPath() + "signInDialog.png", self.__signInDialogFound )
		region.observe( maxWaitTime, True )
		self.__addObserver( region )
			
	# add a new region that is being observed for class to track
	def __addObserver(self, region):
		tempObservers = self.__getObservers()
		tempObservers.append(region)
		self.__setObservers(tempObservers)   // just adds region/observer to list
		
	# stop any observers open on regions tracking
	def __stopObservers(self):
		if len(self.__getObservers()):
			num = 1
			print "stopping " + str(len(self.__getObservers())) + " observers"
			for region in self.__getObservers():
				print "observer " + str(num) + ": stopping..."
				region.stopObserver()
				num += 1
			// self.__setObservers([])  - this line was not in our code, but seems like we should add it
