setup.py missing install_requires

[carlosggarcia]

setup.py does not have a install_requires (https://packaging.python.org/discussions/install-requires-vs-requirements/). This causes that pip will not wait for its dependencies to be installed before attempting to compile NaMaster. In this issue of pip they had a similar problem.
