Add setup method

[nhunzaker]

Tapping into super within the constructor when extending Microcosm feels too low level. What do you think about adding a setup step? Personally, I think it indicates the intent much clearer.

Replaces:

class SolarSystem extends Microcosm {
  constructor(options) {
    super(options)
    this.addStore('planets', Planets)
  }
}

With:

class SolarSystem extends Microcosm {
  setup() {
    this.addStore('planets', Planets)
  }
}

This also eliminates a friction point: remembering to pass options into super().

I like it. Explicit++ 👍

Call the initialize setup method.

Or rename setup to initialize?

[nhunzaker]

Oops. Duh. I called this initialize before, but then changed it to setup because JS class libraries have a history of using init and initialize sort of like a constructor.

👍 I like the change.
