Found at
https://github.com/CytronTechnologies/ESP8266-WiFi-ModuleFour outputs right now. Some inverted states due to some leds hooked up pull up and some pull down.
There also was a handy Windows program to convert html code to the text .h file formatting needed for the .ino included file. convertHtml.exe I tried it and it and it worked as expected.

ESP8266 mDNS responder sample
This is an example of an HTTP server that is accessible
via http://esp8266.local URL thanks to mDNS responder.
Instructions:
- Update WiFi SSID and password as necessary.
- Flash the sketch to the ESP8266 board
- Install host software:
- For Linux, install Avahi (http://avahi.org/).
- For Windows, install Bonjour (http://www.apple.com/support/bonjour/).
- For Mac OSX and iOS support is built in through Bonjour already.
- Point your browser to http://esp8266.local, you should see a response.
