gim::Element element(/* some initialization*/);

//returns a pointer to the direct parent - nullptr if no parent is present
element.parent();

//returns a list of all direct child elements
element.children();

//returns a list of pointers to all direct children with
//the supplied labels

//does the same as the above, except recursively
element.recursiveFindChildren({"label1", "label2", "label3"});

//returns a list of pointers to any direct or indirect parent
//with the supplied labels
