Subject: - access the run number and respective date from the HLT tree
X-Git-Url: http://git.uio.no/git/?a=commitdiff_plain;h=3bee17272e8a18487d186500dabf1ddcbb621d27;p=u%2Fmrichter%2FAliRoot.git

- access the run number and respective date from the HLT tree
  (when offline data are not there, the run number was 0 and the date 19700101)
- moved this access inside the UserExec where the HLT tree is accessible
- removed NotifyRun with the access to the offline tree (that might not always be there)
