[question] What's the proper way to clean up nodes?

[Joe Pea]

Can you give a short example of the proper way to make sure nodes are cleaned up when removed from a scene graph?

@trusktr just leaving this here for the next victim of this problem...

var Dismount = function(node) {
    var aNodes = [];
    if ( !(node instanceof famous.core.Node) )
        throw "node not a Famous#Node";

    var f = function(current) {
        aNodes.push(current);
        var aChildren = current.getChildren();
        for ( var i in aChildren )
            f(aChildren[i]);
    };

    f(node);

    while ( aNodes.length ) {
        var x = aNodes.pop();
        if ( x.isMounted())
            x.dismount();
    }
}

Haven't had any problems with the above recently.
