> As part of the new TermVectorMapper approach to TermVectors, the ensuing patch loads
term vectors and stores the term info by position.  This should let people directly index
into a term vector given a position.  Actually, it does it through Maps, b/c the array based
bookkeeping is a pain given the way positions are stored.  
> The map looks like:
> Map<String,   Map<Integer, TVPositionInfo>>
> where the String is the field name, the integer is the position, and TVPositionInfo is
a storage mechanism for the terms and offsets that occur at a position.  It _should_ handle
multiple terms per position (which is always my downfall! )
> I have not tested performance of this approach.
