/**
* cppmagic - Abuse of the C preprocessor
*
* This contains a bunch of fancy macro techniques such as
* preprocessor-time evaluated conditionals and (quasi) recursion and
* iteration.
*
* It's based on these articles:
* - http://jhnet.co.uk/articles/cpp_magic
* - https://github.com/pfultz2/Cloak/wiki/C-Preprocessor-tricks,-tips,-and-idioms
* and code from the Boost C++ library.
