update multi stage code to accurately skip bbs

moved around classes to packages that make more sense
updated license headers in java files
converted MultiStage logic to FlowManipulator
moved tests to new package location and fixed issues
allow for custom listeners before flowsToExecute
moved validation classes to listener.validation
