Release 4.0.1

‣ Swift 3.0 Support
‣ Updated API to support Swift 3.0 guidelines
‣ Shear Transforms
‣ Perspective Transforms
‣ Radians from Degrees function (and inverse)
‣ Corner Radius with Concave, Convex and Line support
‣ New Color value-type

Note: Since this is a Swift 3 release, I decided to also clean up the API and remove all deprecation warnings. InkKit 2.0 should be considered a new API.
