How do I extend core classes?

If you wish to extend core Amber classes with extra methods, and commit those changes without overwriting the Kernel-Objects.js file (for example), you must set a "Method Protocol" for the method and enter the protocol of "*MyPackage" where "MyPackage" is the package you want to commit that method to. This is exactly like "class extensions" in Monticello in Pharo/Squeak etc and makes sure that the method belongs in the MyPackage package and not in the package of the extended class.
