""" Chapter 9 Exercise 4: Hierarchy of interests.

    "Design a simple hierarchy of interests, along with a data structure to represent it.
    Alter the matchcount function to use the hierarchy to give partial points for matches."

    I implemented a scoring system based upon the activeness levels of the interests.
    A higher score means that people share the same activity levels.
    * see end for more methods of personality based scoring of interests
