Rename .cc/.h files to .cpp/.hpp
As suggested in #219 (closed), this MR renames all .h
files to .hpp
. To be consistent with other open source projects (i.e. lots of BOOST components), our .cc
files have also been renamed to .cpp
.
This MR is built upon the change to #pragma once
in !225 (merged) - that should be merged first.
