  This script transforms the initial condition from
  (tau, x, y, eta) frame to (t, x, y, z) frame. This 
  conversion assumes longitudinal Bjorken expansion
  and transverse still.

  The entropy density in longitudinal-local frame at
  constant proper time tau0 is:
    s(tau0, x, y, eta) = s0(x,y,eta)/tau0 
               = ns0(x,y,eta) <-- trento3d 

  Assuming Bjorken expansion for a short proper time,
    s(tau, x, y, eta) = 1/tau*s0(x,y,eta) 
              = tau0/tau*ns0(x,y,eta) -- (1)

  Expression (1) is transformed into (t, x, y, z) via,
    s'(t0, x, y, z) = 1/tau*ns0(x, y, eta)
        tau = sqrt(t0^2 - z^2)
        eta = 1/2*ln[(t0+z)/(t0-z)]
  where tau0 is absorbed into normalization of ns0
  (see --normalization option of the trento3d model).

  Usage:  
    {:s} trento3d-hdf5-output t0 [list-of-event-id-to-convert]

  For example, to convert all events to t0=1fm/c:
    {:s} ic.hdf5 1.0
  To convert only events #2 and #3 to t0=1fm/c:
    {:s} ic.hdf5 1.0 2 3
