synchronized vector clock

var clock = require('synchronized-clock')()

clock.on('update', function (update) {
  assert(update.value == 'foo')
  assert(update.clocks.length > 0)
})

/**
 * a = {
 *    value : 'string',
 *    clocks : {
 *      'id' : 13,
 *      'id' : 11
 *    },
 * }
 */

clock.on('conflict', function (a, b) {
  assert(a.value != b.value)
  a.ancestor(b)
  a.moreUpdates(b)                       // precedence given to a
  return a                               // or b
                                         // calls clock.on('update') with a or b
})

clock.set('foo')

clockA < clockB                          // works

var stream = clock.createStream()
stream.pipe(net.connect(3000)).pipe(stream)

I don't understand what a.ancestor(b) is for, or a.moreUpdates(b) does.
