frac-ified ECAL cluster shapes mainly used in EXO analysis
Address the code review issues pointed out in #1986
Bug fix. This bug will break the DataMixingModule completely.
Introduced in 7_0_X in August 2013, does not affect 6_2_X or
earlier.
FastTimerService: check the ModuleCallingContext state in the pre/postModuleEventDelayedGet to decide whether or not to pause/resume the dependent module's timer
FastTimerService: migrate to the thread-safe interface of the DQMStore
FastTimerService: create and fill path summary plots only when requested
FastTimerService: identify modules by the unique ModuleDescription::id() instead of the pointer address
FastTimer: fix the behaviour of setStartTime and setStopTime
FastTimerService: fix: reset the stream buffers after each run
FastTimerService: add support for subprocesses
FastTimerService: reimplement summary information printout
FastTimerService: implement plots vs. lumisection and multiple definitions of instantaneous luminosity
FastTimerService: implement plots vs. calibrated luminosity
FastTimerService: implement plots vs. number of pixel clusters
