Example way to use the class below

let rw = RW()
var mDict:[String:String] = ["one":"1","two":"2"]

rw.write("test0",mDict: mDict)
mDict["one"]="g"
rw.read("test0",mDict: &mDict)
print(mDict)


or

let rw = RW()
var mDict = ["one":"1","two":"2","three":3,"more":["stuff":3]] as NSObject

rw.write("test0",mDict: mDict)
var r = mDict as! [String:NSObject]
r["one"]="e"
print("Change \(r)")

rw.read("test0",mDict: &mDict)
print(mDict)


Actually, you can get much more complicated
