Changed MidiPlayer.java to allow the use of external sequencer programs (e.g. Garageband).
Changed Experiment.java to allow user to specify in commandline whether to use default MidiDevice (true), specified MidiDevice (0<variable<MidiDevs.length), or list the available devices on start up.
Changed ExperimentGui.java and SubjectDataPanel.java to add familiarity question if familiarity question isn't included at the presentation of each stimuli.
