86// Implementation version 1 of algorithm class to construct PHOS track segments
87// Track segment for PHOS is list of
88// EMC RecPoint + (possibly) CPV RecPoint
89// To find TrackSegments we do the following:
90// for each EMC RecPoints we look at
91// CPV RecPoints in the radious fRcpv.
92// If there is such a CPV RecPoint,
93// we make "Link" it is just indexes of EMC and CPV RecPoint and distance
94// between them in the PHOS plane.
95// Then we sort "Links" and starting from the
96// least "Link" pointing to the unassined EMC and CPV RecPoints assing them to
97// new TrackSegment.
98// If there is no CPV RecPoint we make TrackSegment
99// consisting from EMC alone. There is no TrackSegments without EMC RecPoint.
100//// In principle this class should be called from AliPHOSReconstructor, but
101// one can use it as well in standalone mode.
102// Use case:
103// root [0] AliPHOSTrackSegmentMakerv1 * t = new AliPHOSTrackSegmentMaker("galice.root", "tracksegmentsname", "recpointsname")
104// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
105// // reads gAlice from header file "galice.root", uses recpoints stored in the branch names "recpointsname" (default = "Default")
106// // and saves recpoints in branch named "tracksegmentsname" (default = "recpointsname")
107// root [1] t->ExecuteTask()
108// root [3] t->SetTrackSegmentsBranch("max distance 5 cm")
109// root [4] t->ExecuteTask("deb all time")
