A simple counter for UIApplication's NetworkActivityIndicator. Use the addActivity method before a request to increase the counter and show the application's network activity indicator. After a request finishes, decrease the counter using the removeActivity method. If the counter reaches 0, the network activity indicator will be hidden.
