IWorkResource

```
public interface IWorkResource
```
Resource that may be registered with a work unit. In general the work unit is responsible of managing the state of such resource. It will inform associated resource about events like begin, rollback, and commit of the resources commit charge (if applicable). After a resource has been closed, it will not be used again. This is the time to release associated internal resources. Resources of a work unit usually has a very defined life time, like a request cycle.
1. begin: first interaction during a unit of work
2. possibly: commit cycle
  1. beforeCompletion: All resources before commit
  2. commit: All resources commit
  3. afterCompletion: All resources after commit
3. rollback: Invoked if the workunit is rollback only at commit time or actually asked to rollback.
4. close: Always called at the end. For all resources. Regardless of failures.
