Detailed Description

Algorithm using an instance of a ITrackFitter to refit the tracks of a given track collection.

Constraint fits are available:

• Option 1 : fit the track with the vertex (first vertex is taken)
• Option 2 : fit the track with the beamspot

Override sysInitialize.

Override sysInitialize from the base class.

Loop through all output handles, and if they're WriteCondHandles, automatically register them and this Algorithm with the CondSvc
