***** UIKit for Gideros Studio ****
**********************************

The original work for this was done by Michael Hartlef. For the original code and license see this thread in the Gideros Forum:

http://www.giderosmobile.com/forum/discussion/578/uikit-plugin-example

UIKit for Gideros Studio is a plugin for iOS that allows usage of UIView, UIButton, UITextField, UIAlertView, UIWebView, UIScrollView, UILabel, UISwitch, UISlider, UIToolbar, UIPickerView, UIImageView,UIActivityIndicatorView, UIProgressView.

Events are dispatched to Gideros Studio.

Note - Andy Bower has ported Wax by Corey Johnson to Gideros Studio. 
This is a bridge between Lua and Objective C, so that all features of Objective C are
now exposed in Gideros Studio.
Please see:

Known issues:

1. Not all methods and properties are implemented.
