Title: Decision tree

+Add DecisionTree MODULE to Classify.ecl.
.Learn from indep + dep discrete datasets, return a model containing branch + final nodes,
return predicted dependent values based on indep dataset and DecTree model.
.Prepared for support different decision tree algorithms.
+Modify Tree.ecl
.Extract split FUNCTION from Decision MODULE, make changes and EXPORT to allow various
splitting criteria.
.EXPORT SplitsGiniImpurityBased Function, returns branch and final nodes.
+Add Test/Explanatory/DecisionTree.ecl
.Show how to build a decision tree model and predict new results.
