Mac support of all APIs
Implement APIs on OSX
Implement mobile-style Xamarin Forms on Mac - more for the purpose of efficient development and debugging on OSX without any emulator than actual Mac app development. Make use of Xamarin Forms cross platform ability, and the similarity between iOS & OSX to enable mobile apps to be compiled, debugged and tested on OSX without emulation before actual mobile platforms. Also encourage third party vendors eg. Realm.io to do the same for the same reason.
ModEdit - Added Implementor and cleaned up formatting, renamed title to better match proposal
