c++ code auto-formatting template/tool needed

#478 (comment)

basically, we dont need to code in a new style we are not used to
as long we have a good auto-formatter template (create one on EclipseIDE or some command line that runs in all OSs to be run just b4 cmake)

of course, after auto-formatted, changing some parts back to personal stile will be replaced later by the auto-formatter :)

I'm definitely not a good C/C++ programmer. I see people use "astyle" or "clang-format". The former require less dependencies and is easier to install.

nice thx!
I think we should use clang-format by the reasons here https://stackoverflow.com/a/841083/1422630
and it can be run automatically on the command line too!

EDIT: I tried some existing styles but didnt like much them (of course, that is a preference thing), ran like:
clang-format -i -style=Google cmdcraft.cpp
anyway, I believe that copying from some existing style and tweaking it could be the best option.
btw, the worst thing I found on the styles seem to be the restriction of the line's width, apparently 80 columns, we dont really need it nowadays (just another opinion anyway xD)

+1 for clang-format. I think it's the way to go nowadays.
