a replacement for a simple express app that accepts a url on it's / endpoint and returns the page's source code to the requesting browser.

• added as a test and to replace a similar application formerly hosted at glitch.
• moved main app away from express and implemented an HTTP Type val.

• currently the / endpoint returns a text string and sets the status and Content-Type headers.
• to replicate the former express app, a get request with a URL query element must be parsed and returned.

<form method="GET" action="/">
        <label>
          URL:
          <input name="url" type="url" required placeholder="URL">
        </label>
        <button type="submit" id="submit">View Source</button>
      </form>
    </main>
  </body>
</html>
