start roughing out test program for preprocessing EDGAR files
split out SEC Header and the HTML document portions of the original

remove leftover &# encodings
- pass in path to output directory
- generate output file name based on input file name and output
  directory
many changes to try and find an approach which works.
going down the path of splitting out tables, converting the HTML to
text then parsing the text using regexs.
bunch of changes to extract data from files
whole bunch of changes to regex to get somewhat close to what actually
needs to be done to locate the data I'm interested in
- expand width to 150 to avoid some line wrapping
- add license notice
