### SquareCam ###

===========================================================================
DESCRIPTION:

SquareCam demonstrates improvements to the AVCaptureStillImageOutput class in iOS 5, highlighting the following features:
- KVO observation of the @"capturingStillImage" property to know when to perform an animation
- Use of setVideoScaleAndCropFactor: to achieve a "digital zoom" effect on captured images
- Switching between front and back cameras while showing a real-time preview
- Integrating with CoreImage's new CIFaceDetector to find faces in a real-time VideoDataOutput, as well as in a captured still image.
     Found faces are indicated with a red square.
- Overlaid square is rotated appropriately for the 4 supported device rotations.
