   Conversion to LaTeX:

   * Converts to the article class

   * If the file is a Word file and has outline levels (i.e. is not a
   Psion 5 file), outline levels 1 to 5 are converted to sectioning
   commands, otherwise headings are just formatted

   * If there is a style with the name 'quotation', the paragraph is
   converted to a quotation environment (other styles/environments
   could be added)

   * Also does formatting commands (italics -> \emph, bold -> \textbf,
   underline -> \underline), and character translation
