  Written by Nochum Sossonko, (nsossonko@hotmail.com)
  
  Based on code initially developed by: Einar Lielmanis, <elfz@laacz.lv>
  http://jsbeautifier.org/
  
  
  You are free to use this in any way you want, in case you find this useful or working for you.
  
  Usage:
  style_html(html_source);
  
  style_html(html_source, options);
  
  The options are:
  indent_size (default 4)          — indentation size,
  indent_char (default space)      — character to indent with,
  max_char (default 70)            -  maximum amount of characters per line,
  brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
  put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.
  unformatted (defaults to inline tags) - list of tags, that shouldn't be reformatted
  indent_scripts (default normal)  - "keep"|"separate"|"normal"
  
  e.g.
  
  style_html(html_source, {
  'indent_size': 2,
  'indent_char': ' ',
  'max_char': 78,
  'brace_style': 'expand',
  'unformatted': ['a', 'sub', 'sup', 'b', 'i', 'u']
  });
