 The QCAR sample apps are organised to work with standard iOS view
 controller life cycles.
 
 * QCARutils contains all the code that initialises and manages the QCAR
 lifecycle plus some useful functions for accessing targets etc. This is a
 singleton class that makes QCAR accessible from anywhere within the app.
 
 * AR_EAGLView is a superclass that contains the OpenGL setup for its
 sub-class, EAGLView.
 
 Other classes and view hierarchy exists to establish a robust view life
 cycle:
 
 * ARParentViewController provides a root view for inclusion in other view
 hierarchies  presentModalViewController can present this VC safely. All
 associated views are included within it; it also handles the auto-rotate
 and resizing of the sub-views.
 
 * ARViewController manages the lifecycle of the Camera and Augmentations,
 calling QCAR:createAR, QCAR:destroyAR, QCAR:pauseAR and QCAR:resumeAR
 where required. It also manages the data for the view, such as loading
 textures.
 
 This configuration has been shown to work for iOS Modal and Tabbed views.
 It provides a model for re-usability where you want to produce a
 number of applications sharing code.
