    init(coordinateString:String) {
        let commaIndex = coordinateString.range(of: ",")!
        let firstElement = coordinateString.substring(to: commaIndex.lowerBound)
        let secondElement = coordinateString.substring(from: commaIndex.upperBound)
        
        latitude = Double(firstElement)!
        longitude = Double(secondElement)!
