Coding style in moose-core

[dilawar]

Would it be helpful to use a fixed coding style to avoid various merge conflict due to different editor settings? If yes, we should pick a style which can be enforced by a tool, e.g. astyle can convert the file into various styles. Tool clang-formatter turns code into google style. Once we are settled on one format, I can run the tool on all files and send a PR with consistent formatting.

Tool astyle support following styles. I prefer -A1 (the first one) but I am OK with any of the following.

    --style=allman  OR  --style=bsd  OR  --style=break  OR  -A1
