/// This method will be called at the method SnapObject() in the VRTK_SnapDrobZone.cs
/// This piece of logic is added by US at Bright vision in the VRTK script;
/// On Snapping this snappable object a bunch of actions should happen excluding
/// the base snappable object because it has different behavior.
///
/// Method functionality:
/// (1) check if it is not the base snappable object because tha base has differnet behavior.
/// (2) Mark the flag of the snappable object to be Snapped.
/// (3) Check if the previous snappable object in the list is not the base snappable object.
/// (4) if the previous snappable object in the list is not the base then disable its collider in order to be still.
/// (5) Turn off the collider of the snap zone of this snappable object in order to avoid colliders conflects.
/// (6) Switch the snap zone(s) of the next snappable object(s).
///
/// Future Version of this method functionality should include:
/// (1) There must be an associate class to declare a level of snap order which the level criteria should be as following:
/// - More than on object can be in the same snap order level.
/// - The whole level has to be completed in order to move on tot he next snap order level.
/// - After completing the snap order level the colliders of all the finished level objects must be disabled.
/// (2) There is something important I forgut but it may be included in the previous point or not.
