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
