  This routine will initialize the species and species values needed for a 
  given setup.   The user should add the 
  implementation of this routine to the setups directory of a simulation 
  that needs to use the multispecies capabilities of the code.

  There two general purpose implementations available in the code, one which sets standard  
  isotope properties for the nuclear burning source terms, and another one for the 
  Ionization source term.

  This routine is called from Multispecies_init, and is called BEFORE
  the call to Simulation_init.
