Simple example of how to use new Away3D stereoscopic rendering

Basic_Stereo.as

// This example uses the stereoscopic rendering feature of Away3D that
// has not yet been merged into any of the main branches. At the time
// of writing this, the below code requires the "stereofeature" branch
// of Away3D.
//
// The running demo can be found here:
// https://dl.dropbox.com/u/1560087/away3d/stereo/Basic_Stereo.html
//
// Note that this feature may or may not make it into main Away3D.

I messed around in away3d with the stereo lens from your code. It's pretty cool.
