Add hierarchical ID (e.g.

Hierarchical IDs have the format "x_y_z_...", e.g. "1_4_2" means: second child of fourth child of first child of page.

The PageObject element gets the special id "pg". The first child of the page starts with id 1. The next child gets the 2 and so on.

Another example: The first child of the page is a Paragraph -> id 1. The second child is a table -> id 2. The first row gets the id 2_1, the
