PMML: Enhance marshaller for DMN's use case

The DMN editor has the ability to import PMML models.

At present the client-side PMML marshaller only supports the basics for Score Cards and Linear Regression Models. It however will need enhancing to support retrieval of the basic information required by DMN for all model types.

The information required is:-

• Model Name
• yamer@redhat.com could you please add the remainder?

PMML 4.4.1 model types:

• AnomalyDetectionModel
• AssociationModel
• BaselineModel
• BayesianNetworkModel
• ClusteringModel
• GaussianProcessModel
• GeneralRegressionModel
• MiningModel
• NaiveBayesModel
• NearestNeighborModel
• NeuralNetwork
• RegressionModel
• RuleSetModel
• Scorecard
• SequenceModel
