[Interop-dev] netjson for meshviewer

[Nemesis]

Hey Moritz,

here's an example, I added some comments although they are not valid
according to the JSON spec, but I added them anyway for explaination
purposes. Keep in mind the spec allows flexibility in placing custom
properties and attributes:

{
    "type": "NetworkGraph",
    "protocol": "batman-adv",
    "version": "batman-adv version here",
    "metric": "tq",
    // custom attributes are allowed
    "timestamp": "2017-09-10T21:15:01",
    "directed": false,
    "multigraph": false,
    "nodes": [
        {
            "id": "62:e3:27:ff:8a:64",
            "node_id": "62e327ff8a64",
            "flags": {
                "gateway": false,
                "online": false
            },

}

I suggest you to read the NetworkGraph section of the spec, is basically
just a page and if you read it you will understand the purpose of the
NetworkGraph object:
http://netjson.org/rfc.html#rfc.section.4

I would really like to rewrite the frontend library
https://github.com/netjson/netjsongraph.js so it would have some of the
features of meshviwer but we haven't been able to accomplish yet and the
attempt to rewrite it in WebGL did not produce the result we are hoped,
but I will keep insisting in the near future when I get a chance.
