Testing

Hi Sam,


This pull request contains a minimum set of changes that fixes both micromegas and superiso. 

It turned out that the file name was not passed correctly in the function. It is modified to be:

fname   ->    c_char_p(fname.encode(ascii))

I also added in the MC8 best fit parameters for the CMSSM in test_point.py , because I have all the existing information for this point. This is good for testing.

I tested that the everything compiles straight out of the box from scratch now, so you can feel confident to merge these little changes :)

Cheers,
Kees
