Problem: inconsistent code style

[kurdybacha]

Solution: copy .clang-format from libzmq as a starting point and run clang-format on the hpp/cpp files.

There is no need to follow exactly what libzmq does as this is header only library but it seems reasonable starting point. It would be good to stick to one style as there is a lot of activity and good ideas lately.
Build changes to follow.

please ignore coverage run with this changes as it is caused by line breaks. Column is now 80 as per clang-format.

Great :) I wanted to apply the formatting myself for some time but did not find the time.

The coverage isn't working properly anyway, unfortunately., And I am not familiar with gcov :(

[kurdybacha]

What do you think about two style changes:
SpaceBeforeParens: Always -> SpaceBeforeParens: false
ColumnLimit: 80 -> ColumnLimit: 85 //as this is header only library and everyone has at least 21inch monitors now
btw I will take a look at coverage issue.

For me that's fine. It's closer to my personal preferences anyway ;)

Thanks for giving the coverage a look. One thing is that the DRAFT parts seem to be completely ignored, they are neither shown as covered nor uncovered.
