    Accessibility check base functionality
    
    This adds AccessibilityCheck class to writer, which perfors the
    accessibility check of the current document to make the document
    conform to PDF/UA requirements.
    
    The first check this adds is check for the "alt" (sometimes also
    called "title") to be present for graphics, OLE objects (charts)
    and shapes.
