/**
 * Flock by Matt Wetmore. Adapted to proscene by Jean Pierre Charalambos. 
 * 
 * A more complex example which interactively enables the selection of a frame
 * "avatar" for the camera to follow.
 * 
 * This example displays the famous artificial life program "Boids", developed by
 * Craig Reynolds in 1986.
 * 
 * Boids under the mouse will be colored blue. If you click on a boid it will be
 * selected as the avatar, useful for the THIRD_PERSON proscene camera mode.
 * 
 * Click the space bar to change between the camera modes: ARCBALL, WALKTHROUGH,
 * and THIRD_PERSON.
 * 
 * Press 'f' to toggle the drawing of the frames' visual hints.
 * 
 * Press 'h' to toggle the mouse and keyboard navigation help.
