			BACKGROUND
			
			A product (Product) has a collection of product SKUs (List<ProductSKU>) associated with it.
			
			Each of those product SKUs may have a collection of product SKU options (List<ProductSKUOption>)
			associated with it.
			
			Each of those product SKU options is represented by a key (ProductSKUOption.Name; e.g., Color) and
			a value (ProductSKUOption.Value; e.g., Red).

			For example, the product Coffee Cup might have multiple product SKUs. One of those product SKUs
			might be CUP-PT. That product SKU might have two product SKU options:

			1. Material: Plastic
			2. Size: Tall
		*/
		
		/*
			STORY

			Given a list of product SKUs for a product (see below), output a list of options available to that
			product. For each option, list the distinct values available to that option.

			For example, if product Coffee Cup has the following three product SKUs, each with two options:

			CUP-PT
			Material: Plastic
			Size: Tall
			
			CUP-PG
			Material: Plastic
			Size: Grande
			
			CUP-AG
			Material: Aluminum
			Size: Grande

			Then the expected output would be:

			Material: Plastic, Aluminum
			Size: Tall, Grande
