The feature of this downloader is its muti-delegate-based monitor mechanism. Instead of using blocks which will casue potential retain cycles, crashes and much higher maintain costs. A muti-delegate monitor is like regular delegate -- clear and easy to maintain. All you need to do is to add your delegate to AHDownloader. You delegate will be kept weakly -- don't need to remove your delegate like when using a notificaiton.

AHDownloader.download(url: String)
/// Get the downoad state for a specific download task
AHDownloader.getState(urlStr: String)
/// Cancel and delete currently downloading tasks and their temporary files.
AHDownloader.deleteUnfinishedTasks(_ urls: [String], _ completion:(()->Void)? )/// Your url string is like a ID for the task. And you differentiate each tasks by their url strings.
/// AHDownloader will remove your delete internally if your delegate gets destoryed.
/// Your delegate is kept weakly inside AHDownloader.
