 ## This is a script that uses Corrade to get the avatar positions and    ##
 ## then aggregates that data to a JSON object that will be read by AJAX. ##
 ##                                                                       ##
 ## The output JSON object that will be read via AJAX is of the form:     ##
 ## {                                                                     ##
 ##    header: ["x", "y", "z"],                                           ##
 ##    positions: [[x1, y1, z1], [x2, y2, z2], ...],                      ##
 ##    names: ["First Resident", "Second Resident", ...],                 ##
 ##    colors: [[0.5, 1, 0.75], [0.3, 0.55, 0.34], ...]                   ##
