rawgit

We've been using rawgit to visualise the html/respec documents we have 
on github, but the service is being shutdown and we should stop using it.

 From rawgit website (https://rawgit.com/):

"RawGit is now in a sunset phase and will soon shut down. It's been a 
fun five years, but all things must end.

GitHub repositories that served content through RawGit within the last 
month will continue to be served until at least October of 2019. URLs 
for other repositories are no longer being served.

If you're currently using RawGit, please stop using it as soon as you can."

Thanks to Dave Raggett for bringing this to my attention.

Best,

Alejandra
