    TeleportObject is an object in the scene that can be "used", which will result in the player being
    teleported to a specified scene (given in the field in the editor).  Overriding the default use button,
    which is the trigger, improves the process.  This is due to the fact that some scenes are loading quickly,
    which then causes the user to be immediatly teleported to the scene since the trigger hasn't had time to be
    unreleased.

    TeleportObject inherits from VRTK_InteractableObject.
