 * Markdown provides an ability to transform markdown into HTML.
 *
 * Basic usage is the following:
 *
 * ```php
 * $myHtml = Markdown::process($myText);
 * ```
 *
 * If you want to configure the parser:
 *
 * ```php
 * $myHtml = Markdown::process($myText, array(
 *     'fn_id_prefix' => 'footnote_',
 * ));
 * ```
 *
