  This problem deserves study; for it exemplifies, in a simple form,
  the main ingredients of computational fluid dynamics, namely the
  effects of:
  * time-dependence,
  * convective transport
  * diffusion (laminar and turbulent)
  * sources, and
  * non-uniform properties.

  The problem-defining data are set in two alternative ways, namely:
  1. using INIT and COVAL for initial and boundary conditions, and
     GRND settings for the properties; and
  2. using In-Form statements, which are easier to understand, and
     provide to freedom to set whatever formulae are desired.

  The results are of course the same, as are (near enough) the
  computer times.

  PHOTON USE commands are provided for ease of display.

  These exploit the possibility of treating the time dimension as
  though it were z-direction distance.

  It is the command IDISPA=1 which effects this.
