/** \file helpers.c
 * Malloc-, Realloc-, Free-wrappers and other small routines.
 * 
 * This file contains small helpful routines that do such omnipresent tasks
 * as allocation memory Malloc(), Malloci(), Mallocii(), reallocating Realloc(),
 * Realloci(), Reallocii() or disallocating Free() with checks error messages
 * in the case of failure. Speed Measuring is initiated InitSpeedMeasure() by setting
 * SpeedStruct entries to zero,
 * completed for output to file CompleteSpeedMeasure() and actually performed
 * SpeedMeasure() herein.\n
 * RemoveEverything() frees all memory that was alloceted during the course of the
 * programme.\n
 * StartParallel() initializes process groups and ranks, while WaitForOtherProcs()
 * waits for the other running processes between the end of init phase and the begin
 * of the calculation.\n
 * Finally, GetRGB() does a colour translation of an RGB value from integer but it's
 * not used anymore.
