* Make suitableType() be Endpoint method With this change it becomes possible to work with endpoint of empty type in packages other than "provider". Also it seems logical for a smart property getter without side effects to be a method rather than a function in different package * Make plan computation work correctly with multi-target domains * fix drawing * drop comments * fix boilerplate header * fix comment * fix the bug with empty map * rework registry to support random lables * serialize->serializeLabel function rename * golint for err variable naming * add additional test * add tests for current case where one resource can generate multiple endpoints * make labels have its own type, add serialization as a method * add comment for exported error * use greater rather than not equal zero * update changelog
