localizeReader is a function that helps provides a standard way to read a resource based on a culture. It takes the object to find the value for and the culture. It will first look for the specific culture ("de-DE"), then fallback to the neutral culture ("de"), then to a default version, then pick the first in the object. It works for objects as…

	var localizeReader = exports;
	(function (localizeReader) {
	localizeReader.get = function(obj, culture){
	var c = (!culture) ? 'default': culture;
	if(obj[c] !== undefined) return obj[c];
	c = c.split('-')[0];
	if(obj[c] !== undefined) return obj[c];
	for (var prop in obj) {
	return obj[prop];
	}
