Class ResourceCoordinator

java.lang.Object
  things.thinger.kernel.ResourceCoordinator

public class ResourceCoordinator
extends java.lang.Object

A resource coordinator. This is mostly a helper for the Kernel. This is where use of IDs went bad in this project. It would have taken a lot of work to fully abstract id operations, so we pretty much just use string representations.
