/**
 * TriggerIncidentAction is an AbstractAction that is used for triggering
 * a simulation incident.  When the action is performed, the incident selected
 * in the incident list table on the Simulation Manager is chosen for triggering.
 * This is done by sending the incident's log number to the Simulation Manager
 * model.  If an incident is not selected in the table, a notification
 * window is shown to the user prompting for an incident to be selected.
 * <br/>
 * <br/>
 * The INCIDENT_LIST_TABLE key must be assigned the IncidentListTable object
 * from the SimulationManagerView object.
