Yeah I worked that out last night  #declare xvec[particle] =
((xvec[particle]*mass[particle])+(xvec[check_particle]*mass[check_particle])
)/(mass[particle]+mass[check_particle]);

There was a few other things wrong so I went for a complete rewrite of the
main code and things are working a lot better now. Added inertia in there
just to polish things off :)
