AnimationControllerManager class

A manager deal with AnimationControllers when given percentage has changed.

AnimationControllerManager's behavior can be described as follows: 1.When the given percentage has changed, it will check whether it is increasing or decreasing. 2.Find the nextAliveControllerEntry which its trigger value is closest and bigger than given percentage. This means if we reach the end, this property will be null, also when it comes to start, the property is first controller with trigger value in given list.

Notice: The item's trigger value in given list must be ascending order!

AnimationControllerManager also can notify which TriggerValWithControllerEntry is active, give the ValueNotifier to notifier property, You can listen and use that in other classes.
