TweenManager

a tweening system very similar to godot. do things like:

var tween = TweenManager.CreateTween();
tween.AddRotation( TreeModel, Rotation.FromRoll( 5 ), 0.2f ).SetEasing( Sandbox.Utility.Easing.QuadraticOut );
tween.AddRotation( TreeModel, Rotation.FromRoll( -5 ), 0.2f ).SetEasing( Sandbox.Utility.Easing.QuadraticInOut );
tween.AddRotation( TreeModel, Rotation.FromRoll( 5 ), 0.2f ).SetEasing( Sandbox.Utility.Easing.QuadraticInOut );
tween.AddRotation( TreeModel, Rotation.FromRoll( 0 ), 0.2f ).SetEasing( Sandbox.Utility.Easing.QuadraticOut );
await tween.Wait();

Log.Info("Done");
