  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.
