Creation of configurations is a slightly delicate business as there are in principle clients which need to be notified of the existance of the configuration. This class is designed to help with some of these issues. The basic decision the author needs to make is whether the configuration being created should be given "local" or "global" scope. If the configuration is to be made generally available to the rest of the program then one should use the "Publish" method below once the configuration construction is complete
