Interfacing with MCP23017

Has anyone successfully used the normal Wire and Adafruit mcp23017 (http://www.componentschip.com/details/microchip-technology/mcp23017-e%2fso.html) drivers on the ESP8266? I've been doing some basic testing but haven't been able to blink an LED yet. 

 

I did see a different library at https://github.com/eadf/esp8266_mcp23017_example but it wasn't in the normal Arduino IDE library format and I didn't want to go to the work of reformatting the files if it wouldn't work.
