@interface devangViewController ()
@end
@implementation devangViewController
@synthesize indicator;

{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
