    this implements a browser for the changes-file (actually, it can display

    any sourceFiles contents).

    See the extra document 'doc/misc/cbrowser.doc' for how to use this browser.

    written jan 90 by claus

    [Class variables:]

        CompressSnapshotInfo            if true (the default), snapshot entries

                                        are also compressed in the compress function.

                                        Some users prefer them to be not compressed.

                                        Set it to false for this.

    Notice:

        this needs a total rewrite, to build up a changeSet from the file

        (which did not exist when the ChangesBrowser was originally written) 

        and manipulate that changeSet.

        This way, we get a browser for any upcoming incore changeSets for

        free. Also, this will put the chunk analyzation code into Change and

        subclasses (where it belongs) and give a better encapsulation and

        overall structure. Do not take this as an example for good style ;-)

        The Change hierarchy is currently been completed, and the changes browser

        will be adapted soon.
