    // The following sample illustrates how to convert HTML pages to PDF format using
    // the HTML2PDF class.
    //
    // 'pdftron.PDF.HTML2PDF' is an optional PDFNet Add-On utility class that can be
    // used to convert HTML web pages into PDF documents by using an external module (html2pdf).
    //
    // html2pdf modules can be downloaded from http://www.pdftron.com/pdfnet/downloads.html.
    //
    // Users can convert HTML pages to PDF using the following operations:
    // - Simple one line static method to convert a single web page to PDF.
    // - Convert HTML pages from URL or string, plus optional table of contents, in user defined order.
    // - Optionally configure settings for proxy, images, java script, and more for each HTML page.
    // - Optionally configure the PDF output, including page size, margins, orientation, and more.
    // - Optionally add table of contents, including setting the depth and appearance.
