Topic: Suggestion 
Subject: Code formatting 
After pondering over the holidays, I decided to use the widely used LLVM code formatting, 
just adapted slightly for 3 spaces and "case" indentation in a "switch" statement. This 
formatting is now very close to our original one. Nevertheless, I did not reformat all 
existing code, since that would screw up the git repository, and you cannot see then anymore 
who wrote which line of code. But having the .clang-format file now in the midas root, all 
NEW files fill follow that standard. 

The CLion editor automatically picks up the .clang-format file if your enable ClangFomrat 
via Preferences -> Code Style -> General -> Enable ClangFormat.

EMACS can also use this file by adding following lines to your .emacs:

(load "<path-to-clang>/tools/clang-format/clang-format.el")
(global-set-key [C-M-tab] 'clang-format-region)

One problem left is if you check out midas on a new machine, you might not have there your 
personal .emacs file. If there is a way to ship a .emacs with midas, which gets 
automatically loaded, I would be happy to put this into the distribution.
