Coding Styleguide Updated

I have updated the Coding Styleguide. Not much has changed, content wise, but the whole thing should be a bit clearer now. Thanks Alex for your remarks.

I recently stumbled across the Joint Strike Fighter Air Vehicle C++ Coding Standards, which have recently been declassified and made available to the public. Might be an interesting read, although it has a whopping 141 pages (including one that has been intentionally left blank).
