* @brief Global definitions
*
* @details
* This header file contains defines and includes which are used in many
* parts of the program. Most notably, it includes the gensvm_memory.h header
* which defines functions for safe memory allocation.
*
* Furthermore, a maximum and minimum function are defined here. These
* functions have their own include guards, to ensure potential linked
* libraries don't conflict with these definitions.
