colorCalculator docs duplicate getColor

looks like they were copied and pasted

colorCalculator is now deprecated with the following message:

colorMixin.colorCalculator has been deprecated. Please colorMixin.colors and colorMixin.colorAccessor instead

The rationale is described in the documentation:

This actually replaces the getColor method!

This is not recommended, since using a colorAccessor and color scale .colors is more powerful and idiomatic d3.

However, I'm open to arguments for keeping colorCalculator. Please comment here if it's something you can't do without! Thank you.

One place where colorCalculator is still useful is in the choropleth, where the reduced data may not have all the keys that the map has, so it's common to do stuff like

       .colorCalculator(function (d) { return d ? usChart.colors()(d) : '#ccc'; })

However, that's partly because of #1268 - since the map data is primary and the crossfilter data is secondary, the choropleth needs to call .getColor for many elements which don't have data. Arguably it should not be calling .getColor but should have an option for the "blank color".

Is there any way to keep the functionality you mention in your last comment for choropleths without using colorCalculator, thus avoiding the deprecate message?
