class SimpleFigure
// simple figure made of a circle for the head and a square for the torso
// the proportions are such that the figure is 3 x radius tall
// and 2 x radius wide, or 2:3
// 
// I would like the figure to be scalable from the main program loop
// 
// I would like the figure to detect collision with another figure
//
// the rectMode is CENTER, so that it can align easily with the circle
//
// it may be better to use a rect that is 3 x radius tall
// so that the width to height ratio is an easy 1:2
// and the center of the figure is easy to calculate using a whole number (integer)
// 
// It would also be useful to define passable color properties
