! Purpose: Initialize residual for scalar variables.
!
! Description: None.
!
! Input: 
!  pRegion              Pointer to region data
!  nVarScal             Number of scalar variables
!  dissScal             Residual due to dissipative scalar fluxes
!
! Output:
!  resScal              Total residual of scalar fluxes
!
! Notes: None.
