// This script will create head and eye rotations for evolver skeletons.
// To use it, make sure your FaceFX.mll plugin is loaded, then delete the
// FBIK and HumanIK controllers from the evolver character's Maya scene.  
// (This is required because we need to set keys on bones prior to exporting 
// bone poses to avoid a strange Maya issue where the script is running too 
// quickly to export the pose correctly.
