Retain loops

[DanijelHuis]

Hi,

AugmentedRealityController and ARViewController are not being deallocated beacuse of these retain loops:

AugmentedRealityController should have "rootViewController" set to weak to avoid retain loop with ARViewController.
@Property (nonatomic, weak) UIViewController *rootViewController;

Delegate in MarkerView should also be declared as weak:
__weak id _delegate;
