    this class implements all kinds of class browsers.

    Typically, it is started with 'SystemBrowser open', but there are many other 

    startup messages, to launch special browsers.

    See the categories 'startup' and 'special search startup' in the classes

    protocol.

    Alse, see the extra document 'doc/misc/sbrowser.doc' or the HTML online doc

    for how to use the browser.

    written winter 89 by claus

    Notice: 

        SystemBrowser is currently being rewritten to be an instance

        of ApplicationModel - this transition is not yet complete and you see

        here intermediate versions of BrowserView/SystemBrowser. 

        All action is (currently) still done here in BrowserView, although the

        SystemBrowsers class methods are used to startup a browser.

        (which is done to make the upcoming switch transparent)

        This will certainly change ...

    PS:

        why did we add more and more here, instead of rewriting ?

        - because nobody pays us for it ;-),

        and the browser is not too bad to use, as long as you do not look into code.

     setting 'RememberAspect' to true makes the browser remember the aspect shown
