+/**
+ `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.

+/**
+ `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

+/**
+ `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

+ ### Usage
+ The three main classes in FMDB are:
+
+ - `FMDatabase` - Represents a single SQLite database.  Used for executing SQL statements.
+ - `<FMResultSet>` - Represents the results of executing a query on an `FMDatabase`.
+ - `<FMDatabaseQueue>` - If you want to perform queries and updates on multiple threads, you'll want to use this class.
+
+ ### See also
+ 
+ - `<FMDatabasePool>` - A pool of `FMDatabase` objects.
+ - `<FMStatement>` - A wrapper for `sqlite_stmt`.

+
+ There are two reasons why this distinction is important. First, the printf-style escape sequences can only be used where it is permissible to use a SQLite `?` placeholder. You can use it only for values in SQL statements, but not for table names or column names or any other non-value context. This method also cannot be used in conjunction with `pragma` statements and the like. Second, note the lack of quotation marks in the SQL.

+ Executing queries returns an `<FMResultSet>` object if successful, and `nil` upon failure.  Like executing updates, there is a variant that accepts an `NSError **` parameter.  Otherwise you should use the `<lastErrorMessage>` and `<lastErrorMessage>` methods to determine why a query failed.
+ 
+ In order to iterate through the results of your query, you use a `while()` loop.  You also need to "step" (via `<[FMResultSet next]>`) from one record to the other.

This  properly escapes any characters that need escape sequences (e.g. quotation marks), which eliminates simple SQL errors as well as protects against SQL injection attacks.

+ 
+ There are two reasons why this distinction is important. First, the printf-style escape sequences can only be used where it is permissible to use a SQLite `?` placeholder. You can use it only for values in SQL statements, but not for table names or column names or any other non-value context. This method also cannot be used in conjunction with `pragma` statements and the like. Second, note the lack of quotation marks in the SQL. The `WHERE` clause was _not_ `WHERE name='%@'` (like you might have to do if you built a SQL statement using `NSString` method `stringWithFormat`), but rather simply `WHERE name=%@`.

+/** To perform queries and updates on multiple threads, you'll want to use `FMDatabaseQueue`.
+
+ Using a single instance of `<FMDatabase>` from multiple threads at once is a bad idea.  It has always been OK to make a `<FMDatabase>` object *per thread*.  Just don't share a single instance across threads, and definitely not across multiple threads at the same time.
+
+ Instead, use `FMDatabaseQueue`. Here's how to use it:
+
+ First, make your queue.
+
+    FMDatabaseQueue *queue = [FMDatabaseQueue databaseQueueWithPath:aPath];
+
+ Then use it like so:
+
+    [queue inDatabase:^(FMDatabase *db) {
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
+
+        FMResultSet *rs = [db executeQuery:@"select * from foo"];
+        while ([rs next]) {
+            //…
+        }
+    }];
+
+ An easy way to wrap things up in a transaction can be done like this:
+
+    [queue inTransaction:^(FMDatabase *db, BOOL *rollback) {
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
