 JS Beautifier

  Originally converted to javascript by Vital, <[e-mail]>

  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,
    indent_level (default 0)         — initial indentation level, you probably won't need this ever,

    space_after_anon_function (default false) — if true, then space is added between "function ()"
            (jslint is happy about this); if false, then the common "function()" output is used.
  braces_on_own_line (default false) - ANSI / Allman brace style, each opening/closing brace gets its own line.

  e.g

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