 * Context Switching. *
***********************/
/*
* Passing a 'true' boolean value to any method that performs an insertion of a node,
* returns the newly created node instead of the parent.
* This operation is called Context Switch.
* Methods that support this context switch are:
* - addChild($child, ...$optionals);
* - prependSibling($sibling, ...$optionals);
* - appendSibling($sibling, ...$optionals);
