Class Description

                                                                      
 VGroupInfo                                                           
                                                                      
 Information on a group of frames.                                    
 A group of frames is defined as a set of frames that follow          
 each other in time, without any "holes" or spaces. It is much easier 
 and faster to search for information in that case.                   
                                                                      

   Copy this into obj

 Increments and updates the group information
 Recalculates the average length of frames

 Resets the group info.
