NestedLithoViewsExtension

open class NestedLithoViewsExtension : MountExtension<Input, State> , OnItemCallbacks<State>

MountExtension to ensure that content with nested LithoViews is properly clearing those LithoViews when the item is unmounted. Since this should only happen when unmounting an item and not when it's being updated, shouldUpdateItem is not overridden (defaulting to super implementation which returns false).
