/*
 * Requires Php-Vars-To-JS-Transformer by Jeffery Way
 * https://github.com/laracasts/PHP-Vars-To-Js-Transformer
 *
 * Import both Javascript (from the aforementioned package), DB, and Hash
 * 
 * We use the token included in the URL to extract the email from the database. 
 * That way we can continue to use the default PW reset methods.
 * The Javascript block is meant to easily deliver the variables to a javascript object for use by an SPA framework.
