MD
  FORTRAN90 version
  A molecular dynamics program.
 
  ND, the spatial dimension, is        3
  NP, the number of particles in the simulation is      500
  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.
