Fixed falsepositive assertions on view controller retain cycles. They are falsepositive in rare cases when UIKit clears screen memory with a delay
Added bottom sheet example in a demo app (third tab on iphone and detail view of split view of a first tab on ipad). This helps us to to test Marshroute's feature not to dismiss a modal screen if it is already dismissed. In a demo this is a case when a Shelf module is opened via a bottom sheet and then dismissed via a swipe down gesture or via a tap on a dimmed area around the bottom sheet. In a demo this first dismissal is invoked via UIKit directly and second one is invoked using Marshroute. This Marshroute's feature works only if second dismissal is triggered asynchronously from the first one (i.e. in a completion block of a first dismissal)

In ResettingTransitionContext initializers the parameter animatingTransitionsHandler was renamed into navigationTransitionsHandler in places where we work with UINavigationController.
AnimatingTransitionsHandler was renamed into BaseAnimatingTransitionsHandler and AnimatingTransitionsHandler became a protocol.
ContainingTransitionsHandler was renamed into в BaseContainingTransitionsHandler and ContainingTransitionsHandler became a protocol.
Got new NavigationTransitionsHandler, SplitViewTransitionsHandler, TabBarTransitionsHandler protocols for cleaner code.
Instead of using UITabBarController и UISplitViewController directly Marshroute now relies on TabBarControllerProtocol и SplitViewControllerProtocol protocols. That allows you to use a custom tab bar or a split view controller (which can not even inherit from UITabBarController or UISplitViewController). Note: we can do the same job for UINavigationController, but this has never been required so far.
Removed WeakBox и StrongBox.
Some marshroutePrint were replaced by marshrouteAssertionFailure
Travis CI was removed
tv os 9.0 is now supported

Add tvos support. Bump minimum supported ios version to 9.0. Add ability to cancel transition undoing if another transition is in progress (enabled by default). Clean some warnings.
