    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.

    This will certainly change ...

     setting this to false, the removeClass function will remove

     classes WITHOUT checking for instances. Otherwise,

     it will check and let you confirm in case there are instances.
