--- Divide this cone shape belonging to volume "voldiv" into ndiv volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume in case of Z divisions. For Z division
 creates all volumes with different shapes and returns pointer to volume that
 was divided. In case a wrong division axis is supplied, returns pointer to
 volume that was divided.
