A VERY basic CRUD op for localStorage from code in voice.gtd

localStorageDb.js

function clearDb(){
	localStorage.clear();
	console.log("Cleared the local storage, god help us all.");
}

//hurrah HTML5 local storage, I'm using a singly linked list as i'm lazy.
function store(msgs){
	if(!localStorage){
		console.error('Browser doesn\'t support local storage, in memory only I\'m afraid');
		return;
	}else{
		var previousMessage = null;
		$.each(msgs,function(i, m){
			if(localStorage.getItem(m.id+".id")==null){
				localStorage.setItem("lastMessage",m.id);
				localStorage.setItem(m.id+".id",m.id);
				localStorage.setItem(m.id+".body",m.body);
				localStorage.setItem(m.id+".sender",m.sender);
				localStorage.setItem(m.id+".from",m.from);
				localStorage.setItem(m.id+".read",m.read);
				localStorage.setItem(m.id+".urgent",m.urgent);
				localStorage.setItem(m.id+".mediaUri",m.mediaUri);
				localStorage.setItem(m.id+".time",m.time);
				//setup the linked list remember the last message will have this null
				localStorage.setItem(m.id+".previousMessage",previousMessage);
				previousMessage = m.id;
			}
		});
		return;
	}
}

//we'll do some clever local storage here later on
function cache(result){
	if(result.hasError){

		return;
	}else{

		});
		store(messages);
		return;
	}
}

//get the local storage messages and render them, stepping backwards through the database.
function getStore(){
	if(!localStorage){
		console.error('Browser doesn\'t support local storage, in memory only I\'m afraid');
		return;
	}else{
		if(localStorage.getItem("lastMessage")!=null){

			}
			return;
		}
		else {
			console.log("Couldn't find a database of messages, have you used this before on another browser? If so open it in there instead.");
			return;

	}
	return;
}

//basic logging to help with the localStorage code.
function storeListener(e){
  if(!e){
   console.log(e);
