documentation

    Generates HTML documentation for a class.

    Although this is normally used with the SystemBrowser

    (classes-generate documentation menu),

    it may be useful on its own, to programatically generate

    up-to-date documents from a classes source.

    This generator extracts the documentation methods source

    (or comment), individual method comments (the first comment in

    a method) and version information to generate a neatly formatted

    HTML page.

    If executable examples (EXBEGIN .. EXEND) are present in the classes 

    documentation category these are also added as executable code

    to the document.

    [instance variables:]

        outStream                               <WriteStream>   internal

        pathToTopOfDocumentation                <String>        will be prepended to links.
