MBTA Homework

FINALLY DONE! :)

Had a hard time figuring out how to calculate number of stops when journey was on different lines, specifically, how to compare indexes between different lines. Also pointing the users specified line (in string form) to the corresponding line array because of the different data types (string --> array)

Also had difficulty visualizing how the intersection of all lines at Park Street could be used to calculate the total number of stops in the journey. Eventually broke the trip into 2 legs, one from starting point to Park street then another from Park Street to the final destination!
