Packaging: Prepare a new pip release

First, we install a bunch of programs:

conda create -y -n py34 python=3.4 numpy scipy paramiko pandas nose pip pyqt qtpy
activate py34
python setup.py develop
pip install pyinstaller

Then, for the actual build:

# do everything in python 3.4 for compatibility reasons
activate py34

# Readme file must be converted from Markdown to ReStructuredText to be displayed correctly on Pip
pandoc --from=markdown --to=rst --output=README.rst README.md

# Next, we must build the distributions (we provide source and binary):
python setup.py sdist
python setup.py bdist_wheel --universal

# Last, make a windows executable file
pyinstaller pyrpl.spec

# Eventually we upload the distribution using twine:
twine upload dist/*
