Detailed Description

WeakVH - This is a value handle that tries hard to point to a Value, even across RAUW operations, but will null itself out if the value is destroyed. this is useful for advisory sorts of information, but should not be used as the key of a map (since the map would have to rearrange itself when the pointer changes).
