! Purpose: read in flow solution for one region (only mixture for now).
!
! Description: the following solution formats are supported:
!              - RocfloMP ASCII
!              - RocfloMP binary.
!
! Input: regions = dimensions of all regions
!        iReg    = region number.
!
! Output: region%levels%mixt%cv        = conservative variables (current grid
!                                        level)
!         region%levels%grid%si/j/kVel = grid speeds (if grid is moving)
!         global%currentTime           = physical time
!         global%resInit               = initial residual
!
! Notes: solution and grid speeds are read in only for the current grid level;
!        solution is also read in for all dummy cells. There is no transfer
!        of data to other processors.
