Design Description
==================

The WorkflowSignalSlotTiein uses the SignalSlot component to emit signals
triggered by the Workflow component.


Main Classes
============

The ezcWorkflowSignalSlotPlugin class extends the abstract base class for
workflow engine plugins, ezcWorkflowExecutionPlugin, and uses an instance of the
ezcSignalCollection class to emit its signals.
