Detailed Description

Used at the start of a sequence to create the EventViews: retrieves filtered collections via menu decision from previous step, merges them and writes out a merged collection to be consumed by HypoAlg(s).

Spawns EventViews for each unique ROI associated to each Decision object in the merged output. Links the EventView and the ROI to each Decision object in the merged output.
