// This script allows you to edit models either with the razor hydras or with your mouse
// This script allows you to grab and move/rotate physical objects with the hydra
//
// Using the hydras :
// grab models with the triggers, you can then move the models around or scale them with both hands.
// You can switch mode using the bumpers so that you can move models around more easily.
// grab physical entities with the right trigger
