Contains the directory name where data are:
* gui directory with graphical user interface files
* openCL directory with OpenCL kernels
* calibrants directory with d-spacing files describing calibrants
* testimages: if does not exist: create it.
This file is very short and simple in such a way to be mangled by installers
It is used by pyFAI.utils._get_data_path
See bug #144 for discussion about implementation
