0.4.0 - Improved Sequences and SpriteKit's Debut

This release brings a lot of improvements to tweens and sequences (deferred start values, relative end values) and the first tween helpers specialized for SpriteKit.

Here is the complete changelog:

Added

• Specialized tween helpers for CGColor and SKColor
• Specialized tween helpers for SpriteKit most commonly used classes: SKNode, SKLabelNode, and SKSpriteNode

Changed

• Tween start and end values are now described through 'travel' enumerations to allow for simple code and greater flexibility
• Start values can now be defined in a deferred way, allowing for tweens to be created in advance, independently from the values they are supposed to work with
• End values can now be defined relatively from the start value
