/// \brief Configuration header file, accessible throughout the model code.
///
/// This header file contains preprocessor definitions accessible throughout the
/// model code. Each implementation file (.cpp file) in LPJ-GUESS should include
/// this header before anything else. Definitions should be placed here if they
/// are of interest when configuring how to build LPJ-GUESS, for instance
/// definitions for enabling/disabling a module, or changing a behaviour which
/// for some reason isn't configurable from the instruction file.
///
/// This file may also contain non-model related code for working around platform
/// specific issues, such as non-standard conforming compilers.
