Swift version of Proximity

Based on ideas of Proximity (https://github.com/revned/proximity), this project creates the same application in Swift, for Mac. In 1.0, application detects bluetooth connectivity to an iDevice in order to know if we are "out of range" or "in range" with the Mac. In later version, I will add something that is more sophisticated. This project is separated into 2 sub projects

MyMac: iOS application to be installed in iOS (will be more fun) Proximity: Mac application to manager your Mac via bluetooth connection to the iDevice
