   3 Sorter to sort one level of input
   4 ===================================
   5 
   6 This parser is adapted from SortText and used to sort text lines which are delimited by a special symbol.  The
   7 sort direction and the column to sort can be specified. For the sort column the type can be specified as "text"
   8 or "date". The delimiters are omitted in the final output.
   9 
  10 Defaults are
  11 delimiter=''
  12 column='1'
  13 column_type='text'
  14 sort_direction='up'
  15 
  16 delimiter is the empty string so that a normal text search is done by default.
