Title: Reorganization of Decision Tree + C45 pruning

- All decision trees make up a module in Calssify.ecl, DecisionTree, which exports the common functions.
- Any specific Decision Tree need to be initialized with different parameters
and has a different way to Learn based upon this parameters.
- C45 pruning was implemented, could be used from Trees.ecl or as a part of C45 Learn.
