+OBShapedButton
+==============
+
+OBShapedButton is a UIButton subclass optimized for non-rectangular button shapes.
+Instances of OBShapedButton respond to touches only in areas where the image that is
+assigned to the button for UIControlStateNormal is non-transparent.
+
+
+Usage
+-----
+
+* Add OBShapedButton.h, OBShapedButton.m, UIImage+ColorAtPixel.h, and UIImage+ColorAtPixel.m
+  to your Xcode project.
+* Design your UI in Interface Builder with UIButtons as usual. Set the Button type to Custom
+  and provide transparent PNG images for the different control states as needed.
+* In the Identity Inspector in Interface Builder, set the Class of the button to OBShapedButton.
+  That's it! Your button will now only respond to touches where the PNG image for the normal
+  control state is non-transparent.
