plotMap : Color extreme values with a different color on maps or heatmaps for several variables

[jalazawa]

we can create a specific legend map for one variable, but we lose the generic legend if we want to plot an another variable.

ex

plotMap(
  mydata, myMapLayout,
  colAreaVar = "MRG. PRICE",
  options = plotMapOptions(
    areaColorScaleOpts = colorScaleOptions(
      breaks = c(0, 100, 200, 20000),
      colors = c("green", "orange", "red")
    )
  )
)

If we choose to plot LOAD then we have a "bad" legend for LOAD.

Can we set quantiles in the parameter "breaks" for all variables ?
Can we set a list of breaks and colors for several variables in areaColorScaleOpts ?
