## 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], ...] ##
## } ##
