Updated ROMS Plotting Package

[arango]

I updated few things in the ROMS plotting package which uses the NCAR/GKS library:

• Added lots of new color palettes derived from Kristen Thyng colormaps. The are palettes for 60, 90, 120, and 240 colors and its inverse order:
  • algae_*.pal and algae_*_flip.pal
  • amp_*.pal and amp_*_flip.pal
  • balance_*.pal and balance_*_flip.pal
  • curl_*.pal and curl_*_flip.pal
  • deep_*.pal and deep_*_flip.pal
  • delta_*.pal and delta_*_flip.pal
  • dense_*.pal and dense_*_flip.pal
  • haline_*.pal and haline_*_flip.pal
  • ice_*.pal and ice_*_flip.pal
  • inferno_*.pal and inferno_*_flip.pal
  • magma_*.pal and magma_*_flip.pal
  • matter_*.pal and matter_*_flip.pal
  • parula_*.pal and parula_*_flip.pal
  • phase_*.pal and phase_*_flip.pal
  • plasma_*.pal and plasma_*_flip.pal
  • solar_*.pal and solar_*_flip.pal
  • speed_*.pal and phase_*_flip.pal
  • tempo_*.pal and tempo_*_flip.pal
  • thermal_*.pal and thermal_*_flip.pal
  • turbid_*.pal and turbid_*_flip.pal
  • viridis_*.pal and viridis_*_flip.pal

• Added logic to process data with two types of vertical coordinate index order:
  • Level k=1 is the bottom and level k=km is the surface: ocean depths are negative, values decrease from top to bottom (ROMS case, Ldecresing=T).
  • Level k=1 is the surface and level k=km is the bottom: ocean depths are positive, values increase from top to bottom.

• Added several scripts to plot from multiple files, aggregated OpenDaP server, and two and three nested grid applications:
  • plt_1grid_ncfiles.sh
  • plt_2grid_ncfiles.sh
  • plt_3grid_ncfiles.sh
  • plt_2grid_opendap.sh
  • plt_2grid_opendap.sh
