Request for support: responsiveness metric

[borisschapira]

A note to remember that if the test is conclusive, it could be relevant to add to this library the support of the responsivement metric.

Current demo implementation, as revised by @anniesullie & @paulirish will catch the value for Interaction / group of events : https://gist.github.com/anniesullie/16814ef9e888fec45e0946da303f55ac

The code to compute the correct value with the "high quantile approximation, option 2" (source) has yet to be written, though.

Thanks for the reminder. Support for the new responsiveness metric is definitely planned. I'll update this issue once it's been added.
