multiFileReader: introduced a file reader class that can read multiple files at once.
multiFileReader: the resync should happen from now on in the new class "multiFileReader" therefore it has been removed from here
multiFileReader: in the old layout the sync class had the possibility to load events by it self from disk. in the new layout the resync class is only receiving events from the  file readers
multiFileReader: the converter has been modified to use the new multi file reader.

LOGIC CHANCE:
before the converter was processing multiple files one after another
now it is merging the files together
the constructor of the file reader has changed therefore the code needed to be corrected
debuging: to see the new structure of the merge files there is now a new file writer which just prints out meta information of the events
offline monitor: now takes the new multi file reader as reader
SCT: checks now only for the event id to compare itself to the TLU
Merge branch 'MultiFilereader'
