ExecCondAlgsAtPreFork()

 Execute the entire conditions sequence during the PreFork step.
This allows saving some memory in AthenaMP jobs, which is particularly

SortInput()

Method that should be post-included after a typicaly configured Athena job
It will read original input files, create a list of Events in memory, sort them and produce

Event information is read from EventInfoTags (stored by default in all Athena data files)
The default sort key value (Lumi) can be oveerriden, as the sorting order
The intermediate Collection file can be inspected using CollQuery cmdline utility
