No indication of required dependencies

[rmbishop]

I was hoping to run the esp8266test.py script, but there is a missing dependency (The "serial" module).

I did not know that I needed to install this module. An indication that this module is needed, and how to install it, would be helpful in the readme of this project.

Just install pyserial librarie using the following command :
pip install pyserial
If you are on a Mac, you should install pip using :
sudo easy_install pip
