Detailed Description

Adds random noise hits to collection of SimTrackerHits of the vertex detector.

======= VTXNoiseClusters ==========
Adds random noise hits to collection of SimTrackerHits of the vertex detector. The number of noise hits are given by the parameter HitDensityPerLayer (hits/cm^2). The noise hits are created with a uniform distribution over the ladder surface. An object of type VXDClusterParameters is added to every hit to describe the extension of the cluster on the ladder surface. The distribution of the cluster sizes is read from ROOT histograms - one per layer.

Parameters

RootHistograms	root file name and histogram names (one per layer)
HitDensityPerLayer	hit densities (hits/cm^2) per VXD layer
VTXCollectionName	collection of VXD SimTrackerhits
RandomSeed	random number seed
