  *                Set this flag to true to prevent removing comments from @text ( minxml and mincss functions only. )
  *
  *   Examples:
  *        vkbeautify.xml(text); // pretty print XML
  *        vkbeautify.json(text, 4 ); // pretty print JSON
  *        vkbeautify.css(text, '. . . .'); // pretty print CSS
  *        vkbeautify.sql(text, '----'); // pretty print SQL
  *
  *        vkbeautify.xmlmin(text, true);// minify XML, preserve comments
  *        vkbeautify.jsonmin(text);// minify JSON
  *        vkbeautify.cssmin(text);// minify CSS, remove comments ( default )
  *        vkbeautify.sqlmin(text);// minify SQL
