+     *  Put this component on an object to define explicitely what colliders it 'owns'. A line of sight
+     *  test performed on the object will not be blocked by any colliders that belong to it.
+     *  
+     *  This component will be useful for example if you're doing LOS tests on a character set up like
+     *  a ragdoll. If the character has Rigidbodies and Colliders on each of its limbs then those limbs
+     *  may block the LOS rays targeting the character. Each limb with a Rigidbody will 'own' any Colliders
+     *  on child objects, but the root of the character doesn't 'own' the limbs.
+     *  
+     *  To fix this you can put this component on the character and assign each limb into the list. You can
+     *  put either the GameObjects with the Rigidbodies or the GameObjects with the Colliders into the list,
+     *  either will work.
