ssb-thread-schema

I made a module for you

var { isRoot, isReply, isFork, isNestedReply } = require('ssb-thread-schema')

const testMsg = {
  type: 'post',
  text: 'oh choice, finally a less janky way to check our stuff',
  root: '%+fBXl12aV1wpAdD62RMl1WRhwthDMuAuHH4iNWgB7jA=.sha256',
  fork: '%PK5aWmXVYJLcmRQTc/6EQE1ht9T5Kb+wi6NgTReMKXI=.sha256'
}
// can be the content of a message or the whole thing

isFork(testMsg)
// => false
isFork.errors
// => helpful errors

isNestedReply(testMsg)
// => true

It's ridiculous this thing doesn't exist already.
I need this to be able to teach #patchbay to handle some of the new replies coming through, but more importantly I wanted to take the spec I started a year ago and give people clear ways to test their understand of the concepts there.

Anyway, enjoy
