/**
 * Focal point for handling upgrade processes.<br>
 * The upgrade manager currently handles two upgrades:
 * to Jsystem 4.8 and to Jsystem 5.1.<br>
 * The two upgrade processes are different in two ways:<br>
 * 1. The changes that were made in scenario file structure are different<br>
 * 2. The way the upgrade process is managed is different.<br>
 * <br>
 * The upgrade to Jsystem 4.8 is done by {@link ScenarioConversion};
 * the upgrade to JSystem 5.1 is embedded in {@link Scenario} and {@link JTestContainer}
 * code and assisted by {@link UpgradeAndBackwardCompatibility}.<br>
 * <br>
 * My assumption is that the upgrade process in later jsystem 
 * versions can not be anticipated so there is no attempt to create a
 * common upgrade class.
