NAME

   MassDiffusivity

SYNOPSIS

   MassDiffusivity(real(in) :: xtemp, 
                    real(in) :: xden, 
                    real(in) :: massfrac, 
                    real(out) :: diffusivity)

DESCRIPTION

   A generic mass diffusivity routine.  Just returns a constant 
   diffusivity from the run-time parameter, 'diff_spec_D'

ARGUMENTS

   xtemp : temperature (in K)
   xden : density (in g/cm**3)
   massfrac : mass fractions of the composition
   diffusivity : mass diffusivity
