input
(
int list_size
4 lists as pointer to array[list_size]
1. current pos array of 'new' positions 
2. current weight array of 'new'weights (may be NULL pointer if you have no weights )
3. reference rpos array of 'old' positions
4. reference rweight array of 'old'weights (may be NULL pointer if you have no weights )
)
output  
(
float lloc[3] center of mass pos
float rloc[3] center of mass rpos
float lrot[3][3] rotation matrix
float lscale[3][3] scale matrix
pointers may be NULL if not needed
