add_key

This function creates a mapping from parent observations to it's descendants (which useful for merging/joining tables).
Either an existing value in the parent observation can be <code>recycle</code>d to it's descendants or a new column 
will be created (if <code>recycle</code> is missing).

Helpers for transforming
XML content into number of tables while preserving parent to child
relationships.
