Detailed Description

Allows a Decision Object to process the current Step over an ROI which was created during a previous Step.

This tools is to be used when this ROI from the previous Step was created inside an EventView.

Exactly ONE ROI must have been written to the TrigRoiDescriptorCollection inside the EventView.

As we cannot write out to BS or POOL ROIDescriptor collections from inside EventViews for technical reasons, the located ROI is copied into a new TrigRoiDescriptorCollection which is produced by this tool
