Custom progress classes should inherit from these classes. They can also be
used as dummy progress classes which simply do nothing.

ZRS(sMonitor object for downloads controlled by the Acquire class.

    This is an mostly abstract class. You should subclass it and implement the
    methods to get something useful.

        not modified.

        This method should not return until the user has confirmed to the user

    in update() to display the current progress.
