Simple class that let's you assign an image and spin it 360deg endlessly
eg. // initialization
ImageSpinner *spinner = [[ImageSpinner alloc] initWithImage:[UIImage imageNamed:@"example.png"]];
// Animation methods
[spinner startAnimation];
[spinner stopAnimation];
// Set another image
[spinner setImage:[UIImage imageNamed:@"example2.png"];
Note: The image will continue spinning to it's original position even when you call stop animation.
