[SciPy-dev] site.cfg.example

[Robert Cimrman]

I have added numpy/site.cfg.example to the SVN. It should contain a list 
all possible sections and relevant fields, so that a (new) user sees 
what can be configured and then just copies the file to numpy/site.cfg, 
removes the unwanted sections and edits the wanted.

If you think it is a good idea and have a section that is not present or 
properly described, contribute it, please :-) When/if the file grows, we 
can put it to the Wiki.

cheers,
