init commit of lab4 gencheeseshop curriculum
move GenCheeseShopv2.java from Methods.intro into lab4
added eduride-library.jar and reference to it in methods.intro
added eduride-library.jar and reference into lab4-gencheeseshop
exports directory to library, and version number to SystemOutTest
probably need a better way to track eduride-library.jar versioning
