Region text

[ghost]

Hi ,
How can we add text inside or on top of the regions?

For Example:-
const regions = [
{
axis: 'x',start:new Date("2018-03-10T00:00:00"), end: new Date("2018-03-10T23:00:00"),
class: 'regionX', label: "Day 1 and 2",
vertical: false,
padding: 0
}
]

Here, label doesn't work? What is the correct api and options to make it work.

c3 version in this repo is v0.4 which is quite old and I think it's not support region text yet. We should update c3 version
