* Lots of small changes related to access.
* Added "access *: ...", made access work for class methods.
* Introduced subclass check: make sure that when calling
  ClassName.methodname(instance, ...), the instance is an instance of
  ClassName or of a subclass thereof (this might break some old code!)
