queue-processor - Queue processor for iOS.

Supports synchronous and asynchronous queue processing. Only one queue is allowed at a time and only one list of items is allowed to be processed at a time.

Example:

JHQueueProcessor* queue = [JHQueueProcessor instance];
id queueItem = *object conforming to JHQueueItem protocol*;
NSArray* queueItems = [NSArray arrayWithObject:queueItem];

// It's possible to add listeners to the queue
[queue addListener:*object conforming to JHQueueListener protocol*];

[queue processQueueAsynchronously:queueItems];

JHQueueItem protocol defines only one method:

- (BOOL) process;

Listeners receive the following events:

- (void) startedProcessingQueue;
- (void) finishedProcessingQueue;
- (void) startedToProcessQueueItem:(id <JHQueueItem>)queueItem;
- (void) finishedProcessingQueueItem:(id <JHQueueItem>)queueItem;
