! Purpose: compute gas dynamic properties of the mixture.
!
! Description: none.
!
! Input: region    = mixture variables and index pointers
!        inBeg     = first value to update
!        inEnd     = last value to update
!        gasUpdate = should the gas variables be also updated?
!
! Output: mixt%dv = dependent variables (p, T, c)
!         mixt%tv = transport variables (viscosity, heat conductivity)
!         mixt%gv = gas variables (cp, molecular mass)
!
! Notes: none.
