Class Description

 HMdcVertexFind

   Vertex finder using weighted LSM with optional Tukey weights

 To use it in a macro just add

 taskset->add(new HMdcVertexFind("name","title",input_mode,tukey)

 where

 input_mode is one of HMdcVertexFind::kSegments or HMdcVertexFind::kHits.
 In the first case HMdcSeg objecst will be used as input (recomended for
 now) while in the secon HMdcHit objects will be used

 As for 'tukey' it can be kTRUE or kFALSE depending on if Tukey weights
 should be used in the minimization. For low multiplicity environments
 like C+C I would recomend kFALSE; at least until I have found better
 parameters for the Tukey weigths minimization.
