Paper: PyFAI: a Python library for high performance azimuthal integration on GPU (J. Kieffer - G. Ashiotis)

Hello, 
I am creating a pull request for the paper for the EuroSciPy 2014 proceedings on behalf of the main author Jerome Kieffer and my self, Giannis Ashiotis
Thank you 
like light -> "similar to visible light"
this is just a proposal but "like light" is colloquial in style
