Tests for functor core algorithms. Work related to FUNCTOR-12. 

A few algorithm classes weren't using BaseFunctorTest. It was changed in this commit. Some further work was needed to make test-objects serializable. And an extra test was included in BaseFunctorTest, to compare (using equals) a functor with a non-functor object.
