Class SQLWrapperUpdater

A class that can be implemented by any custom sql wrapper that should be dynamically generated or updated on every database upgrade

For instance the system QUERYNAME canvas query is regenerated every time the system is updated to account for any new entities and their changes

Typically this implementation can also implement IBaseDataSetProcessorWithDBSave to make sure this is automatically run when dependant items are modified too
