v0.3 - Canvas Group Alpha and Graphic Color

Added two new tween types, canvas alpha and graphics color. Both tweens are UI components.

• Canvas Group Alpha is capable of tweening the alpha value on canvas groups, which is great for fading in groups of elements
• Graphic Color is capable of tweening the color value of any ui graphic, which includes text, image and raw image. It uses a gradient for the color map to allow a full range of RGBA color selection and not just a start and end.

v0.2 - Position, Rotation and Scale

• Very early alpha version with just a tween position, rotation and scale.
• This does include automated tests for tweens as well as a few sample scenes to get you started.
• Still under heavy development.
