> At the moment, ezcWorkflowDatabaseExecution::doSuspend() cleans up the previously suspended
state in the database before persisting. This will be changed to not cleaning up the state
until a workflow execution ends completely. Instead ezcWorkflowDatabaseExecution::doSuspend()
will just create a new snapshot of the workflow execution in the database.
> The existing resume() method will resume a suspended workflow execution from its newest
snapshot. The resumeAt() method that is to be implemented will allow a suspended workflow
execution to be resumed from a previous snapshot (thus cleaning up subsequent snapshots in
the process).
