STATE_group_set_father_group

 

 


   We can call this function with father_group==NULL
   This will mean that this group is at the top of the hierarchy and it doesnt belong to any other group.
   If the function fails it is most likly that we tried to make a loop in hierarchy of the groups
   (for example, groupA father is groupB. groupB father is groupC, and groupC father is groupA ...)
   Returns OK or VR_ERROR.
  
   Example:
  	STATE_group_set_father_group(leg_of_a_chair_group, chair_group);
