split into multiple packages

[asmodehn]

We should make this repo a meta-package

I currently see 3 packages here :

• rostful_turtlesim_example (where we test rostful with basic turtles)
• rostful_rocon_example (where we test rostful with rocon chatter example)
• rostful_rocon_turtle_example (where we test rostful with rocon turtle example)

We will not release these packages, so a simple source layout for testing from source will be sufficient.

First step is to restructure this to be a meta package.
Then we will create an issue for each package implementation.

This is a bad idea, from maintenance perspective.
Closing. Opening new issue with a better idea...
