      Description

      This is a simple utility/wrapper class, that holds the field
      values for recently indexed documents until the NRT reader has
      refreshed, and exposes a "get" API to get the last indexed value per
      id.

      For example one could use this to look up the "version" field for a
      given id, even when that id was just indexed and not yet visible in
      the NRT reader.

      The implementation is fairly simple: it just watches the gen coming
      out of NRTManager and updates/prunes accordingly.

      The class is abstract: you must subclass it and impl the lookupFromSearcher
      method...
