Bug report: without an event cut file, all events are cut for that subsystem

[paulmking]

Environment: (where does this bug occur, have you tried other environments)

• branch (master for latest released): develop
• revision (HEAD for most recent): HEAD
• OS or system: any
• Special ROOT or Geant4 versions?

Steps to reproduce: (give a step by step account of how to trigger the bug)

1. Delete a nearly empty event cuts file which has only the line "EVENTCUTS = 3" (one example is prex_sam_eventcuts.map)
2. Analyze a run with data in that subsystem

Expected Result: (what do you expect when you execute the steps above)

You should see data being processed for those subsystem channels, because there aren't event cuts applied to them.

Actual Result: (what do you get when you execute the steps above)

All of the data for those subsystem channels is cut.

What do I want to have happen:

Make the event cut system default to not cutting the data for a subsystem.
