+/**
+ * @file globals.h
+ * @author Gertjan van den Burg
+ * @date January, 2014
+ * @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.
