guess_cortex_cmap(proptery_name) yields a tuple (cmap, (vmin, vmax)) of a cortical color map
  appropriate to the given property name and the suggested value scaling for the cmap. If the
  given property is not a string or is not recognized then the log_eccentricity axis is used
  and the suggested vmin and vmax are None.
