   7     PURPOSE:
   8         This processor is used to do some spread sheet calculation in a regular wiki
   9     table using only Python. The first column/first line coordinate is A0.
  10 
  11     This code is based on the spreadsheet code posted by Raymond Hettinger and
  12     Richard Copeland at http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/355045
  13     It is also based on the sctable parser by Reimar Bauer (R.Bauer AT fz-juelich.de).
  14 
  15     CALLING SEQUENCE:
  16        {{{
  17        #!sstable [-column_header, -row_header, -show_formular, -format,
  18                   -input_separator, -output_separator ]
  19        }}}
  20 
  21     OPTIONAL INPUTS:
  22        -column_header: additional in the result the column header is shown
  23        -row_header: additional in the result the line number header is shown
  24        -show_formular: if set the formular instead of the result is shown,
  25                        data is arranged in textmode. Blanks in formulars are removed
  26        -format: is used to the set the number of digits for the column values
  27        -input_separator: used to read tables delimitted by something other than the 
  28                          default '||'
  29        -output_separator: used to write tables delimitted by something other than the 
  30                           default '||'
