Mailer without models

You should be able to do something like this. I'm not sure exactly the functionality you needed, but this shows using a form to generate and email with no models involved.

  - added a form on the index.html.erb
  - form submits to /contact route, which I added, pointing to home controller
  - that calls ContactMailer.contact_submit sending in the params from the form post
  - that renders contact_submit.text.erb, which generates the email
