All framework classes have been renamed to use the SihnonFramework_ prefix. The class autoloader now looks for subclasses of the framework classes in the Sihnon_Lib directory, and automatically creates them if they don't exist. The autoloader correctly creates interfaces and abstract classes as needed, by using reflection to check the type of the parent class. All references to classes within the framework now use the Sihnon_ prefix. The PluginFactory supports multiple scan directories, and will search both the framework and subclass class tree to find candidate plugins.
