The official NDT7 Javascript client
libraries. This code works with Node.js >= 12, in a browser, and is the
source for the npm package ndt7.
Includes an example web client and an example node.js client in the examples/
directory. Pull requests gratefully accepted if you would like to write a
more sophisticated web or CLI client that uses the returned measurements to
debug network conditions.

ndt7.discoverServerURLS
discoverServerURLs contacts a web service (likely the Measurement Lab locate service, but not necessarily) and gets URLs with access tokens in them for the client. It can be short-circuted if config.server exists, which is useful for clients served from the webserver of an NDT server.
