[Golist] cycles design continued...

[Moses Gunesch]

Okay here's what I've cooked up:
A couple of simple iterator utils that sit in the managers package,  
Repeater & LinearGoRepeater.

This has allowed me to condense the cycles feature of LinearGo quite a  
bit... the class no longer contains properties cycles, easeOnCycle or  
the two properties that were still needed, extra easing params for  
easeOnCycle and an option to play the tween multiple times forwards  
instead of cycling back-and-forth. All of that has been neatly  
encapsulated so you can now do,

mytween.repeater.cycles = 2;
mytween.repeater.reverseOnCycle = false; // play fwd both times


Let me know what you think of this implementation, the release  
including useFrames is pretty much ready now.

Class Repeater

Constant	Defined by
  	 	INFINITE : uint = 0
[static] Makes code more human-readable, like new  
Repeater(Repeater.INFINITE);
Repeater


  	Property	Defined by
  	 	currentCycle : uint
[read-only] Current cycle starting at 0, which will continue to  
increase up to cycles or indefinitely if cycles is set to  
Repeater.INFINITE (zero).
Repeater
  	 	cycles : uint
Number of times the Repeater will iterate, which can be set to zero or  
Repeater.INFINITE for indefinite repeating.
Repeater
  	 	done : Boolean
[read-only] True if cycles is not infinite and currentCycle has  
reached cycles.
Repeater


Class LinearGoRepeater

  	 	direction : int
[read-only] Current play direction depending on reverseOnCycle and  
currentCycle.
LinearGoRepeater
  	 	easingOnCycle : Function
Storage for optional secondary easing to use on reverse cycles.
LinearGoRepeater
  	 	extraEasingParams : Array
Additional parameters to use with easingOnCycle if the function  
accepts more than four.
LinearGoRepeater
  	 	reverseOnCycle : Boolean
Whether tween direction should reverse every other cycle.
LinearGoRepeater
Class LinearGo

LinearGo(delay:Number,
		duration:Number,
		easing:Function = null,
		extraEasingParams:Array = null,
		repeater:LinearGoRepeater = null, // new!
		useRelative:Boolean = false,
		useRounding:Boolean = false,
		useFrames:Boolean = false, // new!
		pulseInterval:Number)
repeater : LinearGoRepeater
[read-only] A LinearGoRepeater instance that defines options for  
repeated or back-and-forth cycling animation.
Class SequenceBase

repeater : Repeater
[read-only] The sequence's Repeater instance, which may be used to  
make the sequence loop and play more than one time.
SequenceBase
(replaces repeatCount & currentCount properties for Sequence &  
SequenceCA)
