/**
 * CMarkdownParser is a wrapper of {@link http://michelf.com/projects/php-markdown/extra/ MarkdownExtra_Parser}.
 *
 * CMarkdownParser extends MarkdownExtra_Parser by using Text_Highlighter
 * to highlight code blocks with specific language syntax.
 * In particular, if a code block starts with the following:
 * <pre>
 * [language]
 * </pre>
 * The syntax for the specified language will be used to highlight
 * code block. The languages supported include (case-insensitive):
 * ABAP, CPP, CSS, DIFF, DTD, HTML, JAVA, JAVASCRIPT,
 * MYSQL, PERL, PHP, PYTHON, RUBY, SQL, XML
 *
 * You can also specify options to be passed to the syntax highlighter. For example:
 * <pre>
 * [php showLineNumbers=1]
 * </pre>
 * which will show line numbers in each line of the code block.
 *
 * For details about the standard markdown syntax, please check the following:
 * <ul>
 * <li>{@link http://daringfireball.net/projects/markdown/syntax official markdown syntax}</li>
 * <li>{@link http://michelf.com/projects/php-markdown/extra/ markdown extra syntax}</li>
 * </ul>
 *
 * @property string $defaultCssFile The default CSS file that is used to highlight code blocks.
