Subject: Refactor and split up code base

This change splits up the current code base into three different
module:

- opendc-core - This module defines the API which you can use to write
simulatable entities in a topology.
- opendc-omega - This module is the reference implementation of the API
defined the `opendc-core` module.
- opendc-stdlib - This module provides a standard library of entities
which can be used for datacenter simulation.
