Original Source and Fork intent

This NodeJS http2.js module version is a fork of node-http2 hosted on Github originally made by Gábor Molnár and available here: https://github.com/molnarg/node-http2

This fork of node-http2 module named http2.js starts at version 4.0.0 in case previous the repository decides to pick up work again on version 3.x.x.

We are aware that node 8.4.0 now has experimental http2 support via --expose-http2, and we will continue to support the full JavaScript implementation of http2.js at our discretion until HTTP/2 is more fully supported in a broad range of client platforms.
