Contact/demo forms handler for static websites (program)

hugo-mx-gateway provides a RESTful POST endpoint for static contact/demo request pages. It's a simple, yet a powerful tool built for this only-designated purpose, e.g. for use with static sites built using Hugo.

hugo-mx-gateway is built upon a simple request handling workflow:

 * Create an HTML form with a POST action pointing towards the hugo-mx-
   gateway service.
 * For each user request, hugo-mx-gateway automatically retrieves
   information submitted by the user (email, subject, message details...),
   then generates and sends a templated email (based on Go Template to the
   user-provided email address, while bcc'ing a copy of that email to an
   address that you can define for internal tracking and follow up.
 * Once a request is processed (upon success or failure), hugo-mx-gateway
   handles the reply back towards the calling static page by redirecting
   the browser to the origin page with additional URL parameters
   describing the completion status of the processing (e.g.
   /contact.html?status=success&message=request%20submitted). The
   parameters can then be easily retrieved and shown to the user, e.g.
   with a few lines of Javascript within the static page.
