-

-        Updates the cesm_put_data.c routine in the CESM driver to include the correct signs for turbulent heat fluxes and evaporation. Previously we had switched the signs to agree with the image driver and they should instead be in accordance with the sign conventions for coupled models, which differ from those of land surface models. Also, eliminate populating the `l2x_Sl_ram1` field with aero_resist to agree with the VIC 4 implementation in RASM.

 	The VIC image and CESM drivers now may be optionally compiled with OPENMP to enable shared memory thread parallelization. This option should improve the parallel scaling of these drivers by reducing the number of MPI messages and increasing message size.
