Detailed Description

Creates a new (super)-ROI combining windows centred on muons passing eta/pt selection criteria, extracted from a single decision object (which would normally link the FSRoI).

Stores this new ROI in the output container, and links it to the Decision Object

The new EventView spawned by the parent EventViewCreatorAlgorithm of this tool will process in this new ROI.

This tool is mainly intended to create a view for bmumux tracking operations, beginning from muons.
