Message:

Branch 2017/dev_r8126_ROBUST08_no_ghost. Changes to eliminate ghost rows and columns. Currently the halo width is still fixed as 1 but a single variable (nn_hls) has been introduced for the halo-size in preparation for allowing this to vary. nn_hls replaces jpreci and jprecj. These changes have passed full SETTE tests but iceberg exchanges across the north-fold remain untested (SETTE tests only release bergs in the SO) and will require further attention. Note layout.dat now reports the jpi and jpj values for the reporting processor only.
