Use Structured Keys in Shapeless Records

	/**
	* Working with shapeless' records is great. However, you are limited to using only String, Integer, Boolean, and
	* (package) Objects as singleton keys as the singleton machinery requires a stable point (I don't really fully
	* understand this part but I have an intuition). I had asked if there was a way to use a tuple or case-class
	* as a key in the shapeless gitter channel and no one really knew.
	*
	* I was reading the shapeless source for the Witness type and an idea came to mind: since we can use a package Object
	* as a key, what if that key extends a trait (an abstract class can work as well)? Can we use those objects as
	* singleton keys and access the values specified in the trait?
	*
