The Tweener is a powerfull tool to interpolate between different states in parameters over time.
This can be archived in an absolute way, defining a time in which the interpolation needs to be done

op('tweener').AbsoluteTween( target_parameter, target_value, time_in_seconds, curve:string = optional, delay:string = optional )
op('tweener').RelativeTween( target_parameter, target_value, difference_per_second, curve:string = optional, delay:string = optional )

Or call multiple tweens at once by using Tweens and passing a list of dictionaries with the important informations.

op("tweener").AbsoluteTweens( [ {"par" : target_parameter, "end": target_value, "time": optional, "curve" : optional, "delay" : optional} ]
                                , curve:string = optional
                                ,time:float = optional )

op("tweener").RelativeTweens( [ {"par" : target_parameter, "end": target_value, "time": optional, "curve" : optional, "delay" : optional} ]
                                , curve:string = optional
                                ,time:float = optional )

Use the curve-argument to tween using a specific easing-function: https://easings.net/

To stop a specific tween, call the StopFade(target_parameter) or, top stop all tweens, the StopAllFades() method.
