localstorage.factory.js

/**
 * # HTML5 localStorage management service
 *
 * Allows for storing and recalling data from localStorage prefixed with an
 * application specific key. Also handles object stringification and
 * de-stringification as needed
 *
 * Examples:
 *
 *     storageService.set('somekey','somevalue')
 *     storageService.set('somekey',{'key':'value'})
 *     var storedKey = storageService.get('somekey')
 *
