ReferencesOnly test

Checks that algorithms consider not only call-expressions, but refereces (like ClassA::methodA1) too.

Expected refactorings

Member	Move to
ClassA.doSomething1()	ClassB
ClassA.doSomething2()	ClassB

or

Member	Move to
ClassB.mainF()	ClassA

package referencesOnly;

public class ClassA {
    static Object doSomething1(Object o) {
        return "result";
    }

    static Object doSomething2(Object o) {
        return "result";
    }
}
