/*! \file allvars.h
* \brief declares global variables.
*
* This file declares all global variables. Further variables should be added here, and declared as
* 'extern'. The actual existence of these variables is provided by the file 'allvars.c'. To produce
* 'allvars.c' from 'allvars.h', do the following:
*
* - Erase all #define's, typedef's, and enum's
* - add #include "allvars.h", delete the #ifndef ALLVARS_H conditional
* - delete all keywords 'extern'
* - delete all struct definitions enclosed in {...}, e.g.
* "extern struct global_data_all_processes {....} All;"
* becomes "struct global_data_all_processes All;"
