 *
 * this is utility that monkey patch Prism functions to output
 * terminal formatting (it was first created here https://codepen.io/jcubic/pen/zEyxjJ)
 *
 * usage:
 *
 *     you need to include both css and js (it need to be before this file)
 *
 * js code:
 *
 *     code = $.terminal.escape_brackets(code);
 *     code = $.terminal.prism(language, code);
 *
 *     term.echo(code); // or term.less(code) if you include less.js
 *
 * you can also use helper that will create formatter
 *
 *     $.terminal.syntax(language);
 *
 * there is one extra language 'website' that format html with script and style tags
 *
 * by default only javascript markup and css languages are defined (also file extension
 * for them. To have more languages you need to include appropriate js files.
