Detailed Description

fits n vertices in parallel, associating weights for every track-vertex std::pair. The special constructor's arguments take precedence over the SimpleConfigurables.

SimpleConfigurables:

MultiVertexFitter:Debug = 0 MultiVertexFitter:DisplacementLimit = 0.00001 MultiVertexFitter:MaxIterations = 30 MultiVertexFitter:ClaimLostVertices = true MultiVertexFitter:MinimumWeightFraction = 1e-6 MultiVertexFitter:ReviveBelow = 0.3 MultiVertexFitter:DiscardLightWeights = true
