"Ultraproducts and some loose ends"

We'll complete the metric ultraproduct construction, and show that a sofic group embeds in an ultraproduct of symmetric groups equipped with the Hamming distance. If possible we'll tie up some of the loose ends from last time, e.g. the dependence on that constant r, and residually finite groups.
