  HelloServerBearSSL - Simple HTTPS server example

  This example demonstrates a basic ESP8266WebServerSecure HTTPS server
  that can serve "/" and "/inline" and generate detailed 404 (not found)
  HTTP respoinses.  Be sure to update the SSID and PASSWORD before running
  to allow connection to your WiFi network.

  Adapted by Earle F. Philhower, III, from the HelloServer.ino example.
  This example is released into the public domain.
