      Description

      Inspired by Sahin Buyrukbilen's question here:

      http://www.lucidimagination.com/search/document/b68846e383824653/how_to_export_lucene_index_to_a_simple_text_file#b68846e383824653

      I made a simple read/write codec that stores all postings data into a
      single text file (_X.pst), looking like this:

      field contents
        term file
          doc 0
            pos 5
        term is
          doc 0
            pos 1
        term second
          doc 0
            pos 3
        term test
          doc 0
            pos 4
        term the
          doc 0
            pos 2
        term this
          doc 0
            pos 0
      END
      

      The codec is fully funtional – all Lucene & Solr tests pass with
      -Dtests.codec=SimpleText – but, its performance is obviously poor.

      However, it should be useful for debugging, transparency,
      understanding just what Lucene stores in its index, etc. And it's a
      quick way to gain some understanding on how a codec works...
