NodeObj objects are associated with a specific TreeObj object. Each instance of a NodeObj keeps a reference to the TreeObj, thereby preventing the deletion of the TreeObj. Be sure to delete all NodeObj objects prior to deleting the TreeObj.

Do not create a NodeObj directly. Use one of the methods which creates one for you, such as TreeObj.GetNodeObj or NodeObj.GetRelativeNode, as the only ways to create a valid NodeObj object.

	Methods
		Calculation methods ExpVal   Calculates the expected value Evaluate   Calculates the value of an arbitrary formula Variable methods SetVariable   Sets the value of a variable at the node (value must be numeric) SetVariableStr   Sets the value of a variable at the node (value may be a formula) GetVarCount   Counts the number of variable definitions at the node GetVarInfo   Retrieves a VarInfo object for a particular variable definition at the node GetVarInfoStr   Similar to GetVarInfo, but uses the variable name as the lookup, rather than a numeric index Navigation\selection methods GetRelativeNode   Creates a new NodeObj object from a related node GetBranchName   Returns the name of a branch of the node GetBranchNode   Returns a new NodeObj from a specific branch Select   Select this node AddToSelection   Adds this node to the set of currently selected nodes Miscellaneous methods GetOptimal   Returns the index of the recommended strategy at a decision node GetOptimalNode   Returns a NodeObj from the recommended strategy at a decision node GetOneComment   Returns the text of one node comment from a branch
