>   MCMcmUpdater provides utility methods for updating Monticello packages
> from Monticello configurations.
>
> + When Monticello configurations are stored in a repository (or
> repositories), MCMcmUpdater acts as an update stream. It first ensures that
> each configuration map has been loaded in sequence, then updates the last
> configuration map to the most recent version for each specified package, and
> finally loads these versions to produce a fully updated configuration.
> +
> + Currently if a set of packages are unloaded from the image, using this
> class to reload them may cause problems, depending on what dependencies
> those classes have.  Success is not assured.
> +
> + If you wish to not have MCMcmUpdater update packages, there are two ways
> to handle this:
> + 1) To not update any packages not currently in the image, evaluate
> + MCMcmUpdater updateMissingPackages: false
> + Note that any new packages added to the repositories will not be picked
> up when this is turned off.
> + To re-enable updating of missing packages disabled in this way, evaluate
> + MCMcmUpdater updateMissingPackages: true
> + 2) To not updat specific packages, evaluate
> + MCMcmUpdater disableUpdatesOfPackage: <packageName>
> + To re-enable updating of a specific package turned of by method 2,
> evaluate:
> + MCMcmUpdater enableUpdatesOfPackage: <packageName>
> + To re-enable updating of all packages previously disabled by method 2,
> evaluate
> + MCMcmUpdator enableUpdatesForAllPackages
> +
> + Note that work is progressing to automatically not update packages that
> are unloaded.  At this time, this is not turned on.
> +
> + Class Variables definitions:
> +
> + DefaultUpdateURL - this is the URL that will be checked by default for
> updates.  This would be set for a common standard location to check.
> +
> + LastUpdateMap - Keeps track of the last configuration map, so that the
> utility will not have to run through the full history in the repositories
> each time you ask to update.
> +
> + SkipPackages - Keeps track of the specific packages that are not to be
> updated in this image (usually because they were unloaded).
> +
> + UpdateMissingPackages - Indicates if this utility should attempt to load
> packages that are not currently in the system.
