Release Name: 0.0.2

Notes:
This release was completely retooled, many bug fixes and new features added including, LayerMasks, AdjustmentLayers, and FillLayers.

The foundation for this lib is complete and quite usable.  


Changes:
* LayerMask model added. Mask any layer.

* AdjustmentLayer added. Invert, Threshold, Levels, Blur. Proof of concept at the moment, not all of photoshops AjustmentLayer modes have been added as I will have to do some research to emulating similar effects with RMagick.

* FillLayer added. modes supported: SolidColor, Gradient and Pattern.
