• add an if __name__ == '__main__': at the end so that the script can be run as-is (then we can add testing to it eg. if it runs, it passes, similar to SimPEG Examples)
• could you add some comments / minimal docstrings to give a bit more insight as to what each method is doing and what some of the important parameters are? (eg. it is not immediately evident what the first x, y, z are... are they source location?, measurement location?)
• some of the title matching, function matching could be better handled with dictionaries instead of a series of if statements (not as high of priority as the other 2)
