// npcact_ext_clean         NPC ACTIVITIES 6.1
// By Deva Bryson Winblood.   02/13/2006
//=============================================================================
// This function is intended as an item cleanup script for an area.  The NPC
// will pickup any items within 10 meters of where this script is called and
// will walk to a placeable container with specified tag stored in
// sGNBStorageTag on this NPC.  It will place the items within there.  This
// script only works within a single area, so the items to cleanup and the
// placeable to put them in both need to be in the area this script is called
// from.  An important behavior to note is that if the item cannot be reached
// and is a plot item it will simply be instantly copied into the container. If
// it is not plot it will be destroyed.  WARNING: Do not use this in areas where
// you intentionally have placed items on the ground.  This script will cleanup
// those as well if it is fired within 10 meters of them.
