// place this middleware before declaring any routes
app.use((req, res, next) => {
    // This reads the accept-language header
    // and returns the language if found or false if not
    const lang = req.acceptsLanguages('bg', 'en')
    
    if (lang) { // if found, attach it as property to the request
        req.lang = lang
    } else { // else set the default language
        req.lang = 'en'
    }
