SwiftPM support

[TofPlay]

Hi, With Swift 3 it would also be nice to add support for SwiftPM

Articles about SwiftPM:

• Package.swift — The Manifest File
• Developing Packages
• System Modules
• Swift Package Manager Community Proposal

On your README.md add on top and add section for the installation with SwiftPM.
