org.drools.compiler.lang.dsl.DefaultExpanderResolver.addExpander()
Add an expander with the given name, which will be used by looking for the "expander" keyword in the DRL. If a default expander is installed, it will always be returned if none matching the given name can be found. You don't need to use this unless you have multiple expanders/DSLs involved when compiling multiple rule packages at the same time. If you don't know what that sentence means, you probably don't need to use this method.
