/*

An excercise from our Java Programming course:

* Take the data in the file http://www.wellho.net/data/stars.txt
* Read that data and use a factory to create person objects
* calculate their bmis
* produce a sorted list of stars from skinniest up to thickest

See http://melksh.am/j715 (example Station.java) for a template to work from

Sample data:

Scarlett Johansson 5 feet 3.5 inches / 162 cms 110.23-114.64 lbs
