Public Member Functions
	DecisionTree (std::unique_ptr< IVectorizer > vectorizer)
	Constructs a new decision tree object. You have to specify a proper vectorizer object that will be used to calculate values used by considerations (conditions) for the nodes.
void	Print ()
	Prints the decision tree in a very diagnostic fashion onto standard output (cout).
void	Serialize (IDecisionTreeSerializer< ISimulatedGameAction > &serializer) const
	Serializes the content of the tree into the passed serializer object.
void	Deserialize (IDecisionTreeSerializer< ISimulatedGameAction > &serializer)
	Populates the tree based on the given serializer.
void	Construct (Dataset &dataset, int maxDepth=decisionTreeMaxDepth)
	Runs the decision tree construction algorithm (C45). @dataset contains the training data. @maxDepth is The maximum number of nodes deep in the tree. Unless you are out of memory, it is advised to keep the depth relatively unlimited.
virtual std::unique_ptr< ISimulatedGameAction >	GetAction () const override
	Inherited via SimulatedGameHeuristic.
virtual bool	IsHeuristicSituation (const ISimulatedGameUnit &unit) const override final
	Inherited via SimulatedGameHeuristic.
void	SetColumnName (int columnIndex, const std::string &name)
	This will make the Print() function output the name instead of Column[columnIndex]. This name does not affect anything else.
void	SetColumnNames (const std::initializer_list< std::string > &consecutiveNames)
	This will make the Print() function output the names instead of Column[columnIndex]. This name does not affect anything else.
	DecisionTree (const DecisionTree &other)=delete
IVectorizer &	GetVectorizer () const
	Returns the reference to the currently used vectorizer by the DecisionTree. Do not use this method, if you have not assigned any.
void	SetVectorizer (std::unique_ptr< IVectorizer > vectorizer)
	Moves the vectorizer passed as parameter to the DecisionTree. The DecisionTree uses it to provide action via GetAction().
