29 // Description: Discrete Process -- Mie Scattering of Optical Photons
30 // Created: 2010-07-03
31 // Author: Xin Qian
32 // Based on work from Vlasios Vasileiou
33 //
34 // This subroutine will mimic the Mie scattering based on
35 // Henyey-Greenstein phase function
36 // Forward and backward angles are treated separately.
