Try using d3.scale.threshold() for color scales #22

var color = d3.scale.threshold()
.domain([30, 60, 120, 360])
.range(["#ffffcc","#c2e699","#78c679","#31a354","#006837"]);

Automatically use it for range if domain is set and longer than 2 elements?

d3.scale.threshold() is now used when domain array has more than 2 elements.
