/**
 `AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.

 Reachability can be used to determine background information about why a network operation failed, or to trigger a network operation retrying when a connection is established. It should not be used to prevent a user from initiating a network request, as it's possible that an initial request may be required to establish reachability.

 See Apple's Reachability Sample Code ( https://developer.apple.com/library/ios/samplecode/reachability/ )

 @warning Instances of `AFNetworkReachabilityManager` must be started with `-startMonitoring` before reachability status can be determined.

/**
 ## Network Reachability

 The following constants are provided by `AFNetworkReachabilityManager` as possible network reachability statuses.

 enum {
 AFNetworkReachabilityStatusUnknown,
 AFNetworkReachabilityStatusNotReachable,
 AFNetworkReachabilityStatusReachableViaWWAN,
 AFNetworkReachabilityStatusReachableViaWiFi,
 }

 `AFNetworkReachabilityStatusUnknown`
 The `baseURL` host reachability is not known.

 `AFNetworkReachabilityStatusNotReachable`
 The `baseURL` host cannot be reached.

 `AFNetworkReachabilityStatusReachableViaWWAN`
 The `baseURL` host can be reached via a cellular connection, such as EDGE or GPRS.

 `AFNetworkReachabilityStatusReachableViaWiFi`
 The `baseURL` host can be reached via a Wi-Fi connection.

 ### Keys for Notification UserInfo Dictionary

 Strings that are used as keys in a `userInfo` dictionary in a network reachability status change notification.

 `AFNetworkingReachabilityNotificationStatusItem`
 A key in the userInfo dictionary in a `AFNetworkingReachabilityDidChangeNotification` notification.
 The corresponding value is an `NSNumber` object representing the `AFNetworkReachabilityStatus` value for the current reachability status.
 */

///--------------------
/// @name Notifications
///--------------------

/**
 Posted when network reachability changes.
 This notification assigns no notification object. The `userInfo` dictionary contains an `NSNumber` object under the `AFNetworkingReachabilityNotificationStatusItem` key, representing the `AFNetworkReachabilityStatus` value for the current network reachability.

 @warning In order for network reachability to be monitored, include the `SystemConfiguration` framework in the active target's "Link Binary With Library" build phase, and add `#import <SystemConfiguration/SystemConfiguration.h>` to the header prefix of the project (`Prefix.pch`).
