Many of these dependencies come from requirements.txt.

Prefer

sudo apt-get install build-essential python-dev python-pip git-all
sudo pip install --upgrade pip

# Inselect dependencies not provided by requirements.txt
sudo apt-get install libzbar-dev libdmtx-dev python-pyside python-numpy python-opencv

Thanks @edwbaker - this is useful. We should make a distinction between running Inselect as an end user and setting up a development environment.

I have made a few comments on the PR. I will look at this PR again once I have fixed #273 and had a chance to play with 16.04.

These were more end-user instructions, hence making use of the repo libraries.

As an aside: pip installs on Linux for numpy, scipy, skimage, etc. now install binaries instead of compiling from source.
