+/**
+ `AFHTTPSessionManager` is a subclass of `AFURLSessionManager` with convenience methods for making HTTP requests. When a `baseURL` is provided, requests made with the `GET` / `POST` / et al. convenience methods can be made with relative paths.
+
+ ## Subclassing Notes
+
+ Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
+
+ For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
+
+ ## Methods to Override
+
+ To change the behavior of all data task operation construction, which is also used in the `GET` / `POST` / et al. convenience methods, override `dataTaskWithRequest:uploadProgress:downloadProgress:completionHandler:`.
+
+ ## Serialization
+
+ Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
+
+ Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
+
+ ## URL Construction Using Relative Paths
+
+ For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
+
+ Below are a few examples of how `baseURL` and relative paths interact:
+
+    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
+    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
+    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
+    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
+    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
+    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
+    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
+
+ Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

Setting a maximum packet size and delay according to the recommended values (`kAFUploadStream3GSuggestedPacketSize` and `kAFUploadStream3GSuggestedDelay`) lowers the risk of the input stream exceeding its allocated bandwidth. Unfortunately, there is no definite way to distinguish between a 3G, EDGE, or LTE connection over `NSURLConnection`.

Instead, you should consider checking for the "request body stream exhausted" in a failure block, and then retrying the request with throttled bandwidth.

+/**
+ `AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+ ## Subclassing Notes
+
+ This is the base class for `AFHTTPSessionManager`, which adds functionality specific to making HTTP requests. If you are looking to extend `AFURLSessionManager` specifically for HTTP, consider subclassing `AFHTTPSessionManager` instead.
+
+ ## NSURLSession & NSURLSessionTask Delegate Methods
+
+ `AFURLSessionManager` implements the following delegate methods:
+
+ ### `NSURLSessionDelegate`
+
+ - `URLSession:didBecomeInvalidWithError:`
+ - `URLSession:didReceiveChallenge:completionHandler:`
+ - `URLSessionDidFinishEventsForBackgroundURLSession:`
+
+ ### `NSURLSessionTaskDelegate`
+
+ - `URLSession:willPerformHTTPRedirection:newRequest:completionHandler:`
+ - `URLSession:task:didReceiveChallenge:completionHandler:`
+ - `URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:`
+ - `URLSession:task:needNewBodyStream:`
+ - `URLSession:task:didCompleteWithError:`
+
+ ### `NSURLSessionDataDelegate`
+
+ - `URLSession:dataTask:didReceiveResponse:completionHandler:`
+ - `URLSession:dataTask:didBecomeDownloadTask:`
+ - `URLSession:dataTask:didReceiveData:`
+ - `URLSession:dataTask:willCacheResponse:completionHandler:`
+
+ ### `NSURLSessionDownloadDelegate`
+
+ - `URLSession:downloadTask:didFinishDownloadingToURL:`
+ - `URLSession:downloadTask:didWriteData:totalBytesWritten:totalBytesWritten:totalBytesExpectedToWrite:`
+ - `URLSession:downloadTask:didResumeAtOffset:expectedTotalBytes:`
+
+ If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
+
+ ## Network Reachability Monitoring
+
+ Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
+
+ ## NSCoding Caveats
+
+ - Encoded managers do not include any block properties. Be sure to set delegate callback blocks when using `-initWithCoder:` or `NSKeyedUnarchiver`.
+
+ ## NSCopying Caveats
+
+ - `-copy` and `-copyWithZone:` return a new manager with a new `NSURLSession` created from the configuration of the original.
+ - Operation copies do not include any delegate callback blocks, as they often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ session manager when copied.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

+         iOS 7 and iOS 8 differ in NSURLSessionTask implementation, which makes the next bit of code a bit tricky.
+         Many Unit Tests have been built to validate as much of this behavior has possible.
+         Here is what we know:
+            - NSURLSessionTasks are implemented with class clusters, meaning the class you request from the API isn't actually the type of class you will get back.
+            - Simply referencing `[NSURLSessionTask class]` will not work. You need to ask an `NSURLSession` to actually create an object, and grab the class from there.
+            - On iOS 7, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `__NSCFURLSessionTask`.
+            - On iOS 8, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `NSURLSessionTask`.
+            - On iOS 7, `__NSCFLocalSessionTask` and `__NSCFURLSessionTask` are the only two classes that have their own implementations of `resume` and `suspend`, and `__NSCFLocalSessionTask` DOES NOT CALL SUPER. This means both classes need to be swizzled.
+            - On iOS 8, `NSURLSessionTask` is the only class that implements `resume` and `suspend`. This means this is the only class that needs to be swizzled.
+            - Because `NSURLSessionTask` is not involved in the class hierarchy for every version of iOS, its easier to add the swizzled methods to a dummy class and manage them there.
+        
+         Some Assumptions:
+            - No implementations of `resume` or `suspend` call super. If this were to change in a future version of iOS, we'd need to handle it.
+            - No background task classes override `resume` or `suspend`
+         
+         The current solution:
+            1) Grab an instance of `__NSCFLocalDataTask` by asking an instance of `NSURLSession` for a data task.
+            2) Grab a pointer to the original implementation of `af_resume`
+            3) Check to see if the current class has an implementation of resume. If so, continue to step 4.
+            4) Grab the super class of the current class.
+            5) Grab a pointer for the current class to the current implementation of `resume`.
+            6) Grab a pointer for the super class to the current implementation of `resume`.
+            7) If the current class implementation of `resume` is not equal to the super class implementation of `resume` AND the current implementation of `resume` is not equal to the original implementation of `af_resume`, THEN swizzle the methods
+            8) Set the current class to the super class, and repeat steps 3-8
