Multipurpose, radiation hydrodynamics code with self-gravity and the ability to track particles.
The code also converts to a particle-particle-particle-in-cell code.  The is still in a test
phases.  

o Type "make" to make with gcc.  

o The code is currently set up to perform a Sod shock tube test.

o After the code is compiled, run it using ./boxzy in.nml, where in.nml is the provided namelist file. Again
  this is set up for the Sod shock tube test.

o After the simulation has finished, it will provide two outputs, celldump.00000001 and celldump.00000107, where
  the numbers refer to the timestep. Please note that several additions have been made to the code, and your
  test case may not end exactly at 107 -- the updated test case will be added soon, but the comparison will 
  nonetheless be valid.  Go into the analysis directory, and type

  gfortran -o bin_to_ascii bin_to_ascii.f90

  This execultable will now take the formatted celldump files and turn them into ascii format for quick plotting use.
  Execute by typing

  ./bin_to_ascii ../celdump.00000375 T > mysod.dat

  Now GNUPLOT.

  >fmine="mysod.dat"
  >fcomp="sodtest.dat"
  >set xlabel "DISTANCE"
  >set ylable "DENSITY"
  >plot fmine u 2:4, fcomp u 2:4

  The resulting plot will show the density profile.  The curves should be on top of each other, where sodtest.dat is
  a pregenerated file for comparisons.  2:5 will plot the pressure, and 2:($5/$4) will plot a specific energy-like term.

  More soon.
