Connect go code directly to browser and push updates

[adrianco]

First step - build a push.go and push_test.go package that replays the graphjson output using the timestamps to control the rate and send it to a browser via websocket or http/2 server push.

Second step - integrate push.go into a standalone graphpush.go tool that loads a graphjson file, sets up an http endpoint then loops the data at a controlled speed into the connected browser app.

Third step - integrate push.go into edda.go as an option to manage and display the simulation as it happens.
