! Purpose: Initialize flow field for species in a region from scratch.
!
! Description: None.
!
! Input: 
!   pRegion     Region pointer
!
! Output: None.
!
! Notes: 
!   1. Initialize state vector in primitive form. This is done so can compute
!      gas properties based on species mass fractions.
