Installing Toree+Spark 2.1 on Ubuntu 16.04

## 23rd January 2017

At the time of writing, the pip install of toree is not compatible with spark 2.x. We need to use the master branch from git.

Requirements

sudo apt install openjdk-8-jdk-headless

After the First failure (below), I run `make` again and get 

```
make
make build/make/Makefile
make[1]: Entering directory `/home/walkingrandomly/github/sagemath/sage-7.5.1'
make[1]: `build/make/Makefile' is up to date.
make[1]: Leaving directory `/home/walkingrandomly/github/sagemath/sage-7.5.1'

                "cd build/make && ./install 'all'" logs/install.log
