/**
  @brief The PlainTextHTMLMarkupBuilder creates a simple marked up plain text document.

  This class creates a simple plain text markup.

  Text that may be represented as

  @code
    A paragraph with <b>bold</b> text, <i>italic</i> text, and <u>underlined</u> text.
  @endcode

  would be output as

  @code
    A paragraph with *bold* text /italic/ text, and _underlined_ text.
  @endcode

  The markup is intended to be simple, plain and easily human readable. No markup is created for different font-familiy, font-size, foreground or background colors.

  Lists are marked up by preceding the list element with '*' for disc, 'o' for circle, 'X' for square, or a letter or number. Lists are also indented if nested.
  eg:

  @code
    A. One
    B. Two
      o Three
      o Four
        \* Five
        \* Six
    C. Seven
  @endcode

  External references such as external urls and images are represented in the body text as a reference, and references are maintained at the bottom of the output.

  Eg,
  @code
    Here is a link to <a href="http://www.kde.org">KDE</a> and the <a href="http://pim.kde.org">KDEPIM project</a>.
  @endcode

  becomes:

  @code
    Here is a link to KDE[1], and the KDEPIM project[2].
