2.0.0

Well making breaking changes just one day after official release is never good. Unless you have
a A-ha moment and a thing for breaking and remaking things.

The second version of Elmo is a big step forward in writing a simpler code with less boilerplate.

Minor changes:

• CommandUpdate is renamed to Update and placed in it's own package dev.boby.elmo.effect
• Update is moved in it's own packagedev.boby.elmo.pure

Major changes:

The none Command marker is removed from the old CommandUpdate.  The new effect.Update's update method now has the following signature fun update(msg: Message, model: Model): Return<Model, Command>  which has two type constructors :

• Pure(model) which is a type alias for Pair(model,none) 
• Effect(model,cmd) which is a type alias for Pair(model,cmd)

So, where you previously had to write Pair(model,update.none) you can now write Pure(model) . The  benefit is that there is no more need to add one extra command and handle it as Observable.empty() . So this gives you less boilerplate and some minor performance improvements.
