Given a table and an arbitrary number of keys, will successively access subtables using each key in turn, returning the value at the final key. For example, if {t} is { {[1] = {[2] = {[3] = "foo"}}}}, {export.getNested(t, 1, 2, 3)} will return {"foo"}.

If no subtable exists for a given key value, returns nil, but will throw an error if a non-table is found at an intermediary key.]==]
