localStorage.js

// example data
var calls = {
	matt: {
		number: "8587645224",
		id: "call-id-hash",
		timestamp: "08-10-2015"
	},
	mark: {
		number: "8587645232",
		id: "call-id-hash",
		timestamp: "08-10-2015"
	}
};

// append corey's data
calls.corey = { 
	number: "8587645220", 
	id: "call-id-hash", 
	timestamp: "08-10-2015" 
}

// serialize and save to window.localStorage
var str = JSON.stringify(calls); // object to string 
localStorage.setItem("calls", str); // set string to local storage

// get from localStorage and decode
var out = localStorage.getItem("calls");
var obj = JSON.parse(out);
