For users, the easiest way to get pyiso is with pip:
pip install pyiso
cd pyiso python setup.py install
Pyiso depends on pandas so be prepared for a large install.
Windows Users: If you are unable to setup pyiso due to issues with installing or using numpy, a dependent package of pyiso, try installing a precompiled version of numpy found here: http://www.lfd.uci.edu/~gohlke/pythonlibs/
pip uninstall pyiso
