Events through 3 ways

[jonasdacruz]

I think that we have to separate Event concept in 3 different ways.

1- Global or App.
2- Data, HTTP or Network.
3- User interaction.

So, my proposal would be to follow using current iris.on, iris.off, iris.notify as App Events.

Create events about Network traffic within Resource components and in the other hand add new methods in UI and Screen components, being these the User interaction events.

We would add a new collection of methods such as self.on, self.off, self.notify, doing each one just reachable in their context.
