- added the DCA for the HLT tracks, as calculated by the HLT reconstruction, however...

  as not all ESD files contain this information and the distribution will be empty for older HLT runs.
  Besides the DCA value differences are minor between what the task calculates at the momemt and what
  the HLT reconstruction delivers. The commit is for completion of information.
