Detailed Description

PropIndexTH builds a positional indexer. This class is a destination TextHandler. It expects the position of the token to be given (not counted) and will index certain properties if passed in the PropertyList. PropertyList *must* have one property called "position" with the token position. Any and ALL other properties of type STRING will be indexed at the same position as the token, but added after the token. This is usually the last object in TextHandler chain. If a property should NOT be indexed, remove it before it gets here.
