/** LOTAnimationTransitionController
 *
 *  This class creates a custom UIViewController transition animation
 *  using a Lottie animation to transition between two view controllers
 *  The transition can use custom defined layers in After Effects for to/from
 *
 *  When referencing After Effects layers the animator masks or transforms the to/from viewController
 *  with the referenced layer.

 The initializer to create a new transition animation.
 
 @param animation The name of the Lottie Animation to load for the transition

 If no layer is specified then the screenshot is added behind the Lottie Animation
 
 @param toLayer The name of the custom layer to mask the toVC screenshot with.
 If no layer is specified then the screenshot is added behind the Lottie Animation
 and a fade transition is performed along with the Lottie animation.
 
 @param applyAnimationTransform A boolean that determines if the custom layer should
 have the transform animation from the After Effects layer applied to it. If NO the
 layer will be masked by the After Effects Layer
