// This script allows you to grab and move/rotate physical objects with the hydra
//
// Using the hydras :
// grab physical entities with the right trigger
// Grab's physically moveable entities with the hydra- works for either near or far objects. User can also grab a far away object and drag it towards them by pressing the "4" button on either the left or ride controller.
