Enabled user tweaking of isolation parameters

[JacobGlennAyers]

• Encapsulated the "steinberg" and "simple" techniques into a master "isolate" function that is defined by the passed in isolation parameters
• Renamed calc_local_scores() to generate_automated_labels()
• Reworked generate_automated_labels() to take in the isolation parameters dictionary
• Reworked local_score_visualization() to take in the isolation parameters as well as the master isolate() function.
• Deleted the calc_local_scores2() and local_score_visualization2() functions that were designed to demonstrate the simple isolation technique.
• updated jupyter notebook tutorial to demonstrate above changes.
• removed the second howler monkey example clip visualizations as well as the demonstration of "catch" scores since they seem redundant and inflated the size of the tutorial

Had to do some merge conflict resolution since I hadn't pulled Shravan's most recent changes on my local repo. Should be handled now
