This line will cause the scanner to call 
Plugins::SimpleLibraryViews::Plugin->initPlugin(). But it will NOT 
automatically create a scan task. Therefore you should call 
Slim::Music::Import->addImporter() to tell the scanner that you have an 
importer, what type it is (file importer, post processing etc.), and how 
to call it.

See eg.
