void VariableTree::insertNode	(	unsigned	parent_var,
		unsigned	introduced_var,
		bool	direct_output
	)

Inserts a new node into the variable tree.

Inserts a new node into the variable tree, which is appended as child of the first argument of this method.

Parameters:

`[in]`	parent_var	Parent node of the new node.
`[in]`	introduced_var	New node or variable respectively to be inserted.
`[in]`	direct_output	Indicator if new node or variable respectively has direct output in its corresponding ForExpression, i.e. `true` if direct output is present, `false` otherwise.

Return values:

void
