Use space not tabs in code

[vtcloud]

Hi,
it would be nice to follow the python style guide (https://www.python.org/dev/peps/pep-0008/#tabs-or-spaces) and use spaces instead of tabs. The mixing of both is not possible in python 3. There are a sections in there code where tabs and spaces are mixed (e.g. ENIIGMA/Continuum/Fit.py).
Thank you.

Hi,
the current version of the ENIIGMA code has worked fine for me in both Python 2 and 3. But I'll convert all tabs into space, as this is the recommendation for Python 3.
Thanks for your comment.
