Implementation proposal for Z-Components: ZPoller, ZAgent, ZStar, ZActor, ZProxy

Hello, 

Here is a proposal of implementation for several Z-components: ZPoller, ZAgent, ZStar, ZActor and ZProxy.

I use it for my project and it may be of some use for you too. I would be interested by your comments, if I am aiming at the right direction, and if not, what would be your proposal solutions.
