Adding nix Support

[dmssargent]

Linux support depth should be broadened to include more teams focusing on a budget.
This should include

• standard distro updating and installing packages to get the system ready

i.e.

sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get -y dist-upgrade
sudo apt-get install openjdk-7-jdk git build-essential python other-things

• checking that everything works
• writing *nix documentation
• Anything else that should be included for *nix
