Add Equatable to CLLocationCoordinate2D

CLLocationCoordinate2D+Equatable.swift

import CoreLocation

extension CLLocationCoordinate2D: Equatable {}

public func ==(lhs: CLLocationCoordinate2D, rhs: CLLocationCoordinate2D) -> Bool {
    return lhs.latitude == rhs.latitude && lhs.longitude == rhs.longitude
}

Should probably update the float equality to use .ulpOfOne instead of == at some point
