/**
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits
 *    but "incrementing" them by 1 (only in the case of a timestamp collision).

Function::property = (prop, desc) ->
  Object.defineProperty @prototype, prop, desc

class Person
  constructor: (@firstName, @lastName) ->
  @property 'fullName',
    get: -> "#{@firstName} #{@lastName}"
    set: (name) -> [@firstName, @lastName] = name.split ' '
