Dumping an Og::Collection using to_yaml or YAML::dump results in a hard to track error: TypeError: can't dump anonymous class Class. This is because Collection has an instance variable which contains a literal Class. This patch fixes the problem, by storing the member_class as a String, and converting as necessary in the code.
