// This program reads in some Circles and Rectangle Objects
// from a file into a HashSet and then prints them out.
//
// In data file there is either a 1 or a 2 separating the
// objects. If 1 it is a circle and has a radius after it.
// If 2 it is a rectangle and so has a width and height
// after it.
