// Class for creating URLs. It handles URL encoding of parameters.
//
// Usage example:
//
// GTMURLBuilder *URLBuilder =
//     [GTMURLBuilder builderWithString:@"http://www.google.com"];
// [URLBuilder setValue:@"abc" forParameter:@"q"];
// NSURL *URL = [URLBuilder URL];
//
// NOTE: Apps targeting iOS 8 or OS X 10.10 and later should use
//       NSURLComponents and NSURLQueryItem to create URLs with
//       query arguments instead of using this class.
