The NSDictionary(GCKAdditions) category provides convenience methods for safely looking up values of various types in NSDictionaries.
These methods are particularly useful for working with JSON data objects.
Instance methods are available to look up values of types such as NSString, NSInteger, NSUInteger, double, BOOL, NSDictionary, NSArray, and NSURL, with options for providing a default fallback value.
