Improving dependencies in flows

Currently, flow dependencies are limited to the software version. However, some of them also require additional dependencies. For example, flow 191 requires also the installation of multiBoostAB from the package manager.

From the implementation point of view I don't know how feasible is to know the package of a class in Java though.

You can get the name of a class's package using Java introspection. Only for classes that are loaded, though.

I did some modifications in the Weka package and I was able to compile it. However, when I install it using the package manager in Weka 3.7.11 it says that it's not compatible. I guess that some black magic is doing behind the scenes to create the current OpenWeka package, so probably additional steps are needed.

Nevertheless, I add here these lines from WekaAlgorithm.create() for my own record :)

Package packageOfClassifier = classifier.getClass().getPackage();
        if (packageOfClassifier!=null){
            dependencies += "; " + packageOfClassifier.toString() + "_" + packageOfClassifier.getImplementationVersion();
        }
