MD
  FORTRAN77 version
  A molecular dynamics program.
 
  NP, the number of particles in the simulation, is      500
  ND, the spatial dimension, is        3
  STEP_NUM, the number of time steps, is      500
  DT, the size of each time step, is   0.100000    
 
  At each step, we report the potential and kinetic energies.
  The sum of these energies should be a constant.
  As an accuracy check, we also print the relative error
  in the total energy.
