 JS Beautifier

      http://jsbeautifier.org/

  Originally converted to javascript by Vital, <vital76@gmail.com>
  "End braces on own line" added by Chris J. Shull, <chrisjshull@gmail.com>

  You are free to use this in any way you want, in case you find this useful or working for you.

  Usage:
    js_beautify(js_source_text);
    js_beautify(js_source_text, options);

  The options are:
    indent_size (default 4)          - indentation size,
    indent_char (default space)      - character to indent with,
    preserve_newlines (default true) - whether existing line breaks should be preserved,
    max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,

    jslint_happy (default false) - if true, then jslint-stricter mode is enforced.

            jslint_happy   !jslint_happy
            ---------------------------------
             function ()      function()

    brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "expand-strict"
            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.

            expand-strict: put brace on own line even in such cases:

                var a =
                {
                    a: 5,
                    b: 6
                }
            This mode may break your scripts - e.g "return { a: 1 }" will be broken into two lines, so beware.

    space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)",

    unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"

    e.g

    js_beautify(js_source_text, {
      'indent_size': 1,
      'indent_char': '\t'
    });

 Style HTML

  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',
