+/**
+ `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: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.

+
+AFNetworking is a delightful networking library for iOS and Mac OS X. It's built on top of the [Foundation URL Loading System](http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/URLLoadingSystem/URLLoadingSystem.html), extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.
+
+Perhaps the most important feature of all, however, is the amazing community of developers who use and contribute to AFNetworking every day. AFNetworking powers some of the most popular and critically-acclaimed apps on the iPhone, iPad, and Mac.
+
+Choose AFNetworking for your next project, or migrate over your existing projects—you'll be happy you did!

+
+## Installation
+AFNetworking supports multiple methods for installing the library in a project.
+
+## Installation with CocoaPods
+
+[CocoaPods](http://cocoapods.org) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like AFNetworking in your projects. See the ["Getting Started" guide for more information](https://github.com/AFNetworking/AFNetworking/wiki/Getting-Started-with-AFNetworking). You can install it with the following command:
+
+```bash
+$ gem install cocoapods
+```
+
+> CocoaPods 0.39.0+ is required to build AFNetworking 3.0.0+.
+
+#### Podfile
+
+To integrate AFNetworking into your Xcode project using CocoaPods, specify it in your `Podfile`:
+
+```ruby
+source 'https://github.com/CocoaPods/Specs.git'
+platform :ios, '8.0'
+
+pod 'AFNetworking', '~> 3.0'
+```
+
+Then, run the following command:
+
+```bash
+$ pod install
+```
+
+### Installation with Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
+
+You can install Carthage with [Homebrew](http://brew.sh/) using the following command:
+
+```bash
+$ brew update
+$ brew install carthage
+```
+
+To integrate AFNetworking into your Xcode project using Carthage, specify it in your `Cartfile`:
+
+```ogdl
+github "AFNetworking/AFNetworking" ~> 3.0
+```
+
+Run `carthage` to build the framework and drag the built `AFNetworking.framework` into your Xcode project.
+

+- `AFNetworkReachabilityManager`
+
+## Usage
+
+### AFURLSessionManager
+
+`AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+#### Creating a Download Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
+    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
+    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
+} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
+    NSLog(@"File downloaded to: %@", filePath);
+}];
+[downloadTask resume];
+```
+
+#### Creating an Upload Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
+NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"Success: %@ %@", response, responseObject);
+    }
+}];
+[uploadTask resume];
+```
+
+#### Creating an Upload Task for a Multi-Part Request, with Progress
+
+```objective-c
+NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
+        [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
+    } error:nil];
+
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
+
+NSURLSessionUploadTask *uploadTask;
+uploadTask = [manager
+              uploadTaskWithStreamedRequest:request
+              progress:^(NSProgress * _Nonnull uploadProgress) {
+                  // This is not called back on the main queue.
+                  // You are responsible for dispatching to the main queue for UI updates
+                  dispatch_async(dispatch_get_main_queue(), ^{
+                      //Update the progress view
+                      [progressView setProgress:uploadProgress.fractionCompleted];
+                  });
+              }
+              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

+                  }
+              }];
+
+[uploadTask resume];
+```
+
+#### Creating a Data Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://httpbin.org/get"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"%@ %@", response, responseObject);
+    }
+}];
+[dataTask resume];
+```
+
+---
+
+### Request Serialization
+
+Request serializers create requests from URL strings, encoding parameters as either a query string or HTTP body.
+
+```objective-c
+NSString *URLString = @"http://example.com";
+NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};
+```
+
+#### Query String Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];
+```
+
+    GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### URL Form Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/x-www-form-urlencoded
+
+    foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### JSON Parameter Encoding
+
+```objective-c
+[[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/json
+
+    {"foo": "bar", "baz": [1,2,3]}
+
+---
+
+### Network Reachability Manager
+
+`AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.
+
+* Do not use Reachability to determine if the original request should be sent.
+	* You should try to send it.
+* You can use Reachability to determine when a request should be automatically retried.
+	* Although it may still fail, a Reachability notification that the connectivity is available is a good time to retry something.
+* Network reachability is a useful tool for determining why a request might have failed.
+	* After a network request has failed, telling the user they're offline is better than giving them a more technical but accurate error, such as "request timed out."
+
+See also [WWDC 2012 session 706, "Networking Best Practices."](https://developer.apple.com/videos/play/wwdc2012-706/).
+
+#### Shared Network Reachability
+
+```objective-c
+[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
+    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
+}];
+
+[[AFNetworkReachabilityManager sharedManager] startMonitoring];
+```
+
+---
+
+### Security Policy
+
+`AFSecurityPolicy` evaluates server trust against pinned X.509 certificates and public keys over secure connections.
+
+Adding pinned SSL certificates to your app helps prevent man-in-the-middle attacks and other vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged to route all communication over an HTTPS connection with SSL pinning configured and enabled.
+
+#### Allowing Invalid SSL Certificates
+
+```objective-c
+AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
+manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production
+```

+/**
+ `AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a session task has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
+
+ You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
+
+    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
+
+ By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
+
+ See the Apple Human Interface Guidelines section about the Network Activity Indicator for more information:
+ http://developer.apple.com/library/iOS/#documentation/UserExperience/Conceptual/MobileHIG/UIElementGuidelines/UIElementGuidelines.html#//apple_ref/doc/uid/TP40006556-CH13-SW44

+ * Welcome to CocoaLumberjack!
+ *
+ * The project page has a wealth of documentation if you have any questions.
+ *
+ * If you're new to the project you may wish to read "Getting Started" at:
+ * Documentation/GettingStarted.md
+ *
+ * Otherwise, here is a quick refresher.
+ * There are three steps to using the macros:
+ *
+ * Step 1:
+ * Import the header in your implementation or prefix file:
+ *
+ * #import <CocoaLumberjack/CocoaLumberjack.h>
+ *
+ * Step 2:
+ * Define your logging level in your implementation file:
+ *
+ * // Log levels: off, error, warn, info, verbose
+ * static const DDLogLevel ddLogLevel = DDLogLevelVerbose;
+ *
+ * Step 2 [3rd party frameworks]:
+ *
+ * Define your LOG_LEVEL_DEF to a different variable/function than ddLogLevel:
+ *
+ * // #undef LOG_LEVEL_DEF // Undefine first only if needed
+ * #define LOG_LEVEL_DEF myLibLogLevel
+ *
+ * Define your logging level in your implementation file:
+ *
+ * // Log levels: off, error, warn, info, verbose
+ * static const DDLogLevel myLibLogLevel = DDLogLevelVerbose;
+ *
+ * Step 3:
+ * Replace your NSLog statements with DDLog statements according to the severity of the message.
+ *
+ * NSLog(@"Fatal error, no dohickey found!"); -> OSSLogError(@"Fatal error, no dohickey found!");
+ *
+ * DDLog works exactly the same as NSLog.
+ * This means you can pass it multiple variables just like NSLog.

+/**
+ * Define the standard options.
+ *
+ * We default to only 4 levels because it makes it easier for beginners
+ * to make the transition to a logging framework.
+ *
+ * More advanced users may choose to completely customize the levels (and level names) to suite their needs.
+ * For more information on this see the "Custom Log Levels" page:
+ * Documentation/CustomLogLevels.md
+ *
+ * Advanced users may also notice that we're using a bitmask.
+ * This is to allow for custom fine grained logging:
+ * Documentation/FineGrainedLogging.md
+ *
+ * -- Flags --
+ *
+ * Typically you will use the LOG_LEVELS (see below), but the flags may be used directly in certain situations.
+ * For example, say you have a lot of warning log messages, and you wanted to disable them.
+ * However, you still needed to see your error and info log messages.
+ * You could accomplish that with the following:
+ *
+ * static const DDLogLevel ddLogLevel = DDLogFlagError | DDLogFlagInfo;
+ *
+ * When LOG_LEVEL_DEF is defined as ddLogLevel.
+ *
+ * Flags may also be consulted when writing custom log formatters,
+ * as the DDLogMessage class captures the individual flag that caused the log message to fire.
+ *
+ * -- Levels --
+ *
+ * Log levels are simply the proper bitmask of the flags.
+ *
+ * -- Booleans --
+ *
+ * The booleans may be used when your logging code involves more than one line.
+ * For example:
+ *
+ * if (LOG_VERBOSE) {
+ *     for (id sprocket in sprockets)
+ *         DDLogVerbose(@"sprocket: %@", [sprocket description])
+ * }
+ *
+ * -- Async --
+ *
+ * Defines the default asynchronous options.
+ * The default philosophy for asynchronous logging is very simple:
+ *
+ * Log messages with errors should be executed synchronously.
+ *     After all, an error just occurred. The application could be unstable.
+ *
+ * All other log messages, such as debug output, are executed asynchronously.
+ *     After all, if it wasn't an error, then it was just informational output,
+ *     or something the application was easily able to recover from.
+ *
+ * -- Changes --
+ *
+ * You are strongly discouraged from modifying this file.
+ * If you do, you make it more difficult on yourself to merge future bug fixes and improvements from the project.
+ * Instead, create your own MyLogging.h or ApplicationNameLogging.h or CompanyLogging.h
+ *
+ * For an example of customizing your logging experience, see the "Custom Log Levels" page:
+ * Documentation/CustomLogLevels.md
