Today we discuss something you'll need for your project - how to calculate
the distance from a point (a mouse click position) to an object (a line,
a rectangle, a circle, or a polygon).  You'll need this because when a user
clicks at a point to delete an object, you'll need to figure out which
object they're trying to delete.  This means that you'll have to go through
your list of objects to find one/ones that is/are close to the clicked point.
