Should Solution and Organization extend MetaRequirement?

[mlhaufe]

Schema comparison:

Solution
	id
	description
	name
	organization
	slug
	... collections
	
Organization
	id
	description
	name
	slug
	... solutions

MetaRequirement
	id
	name
	statement
	solution
	lastModified
	isSilence

Note statement vs description. Related (#368)

There is no such thing as an Organization or Solution being a silence requirement. An additional challenge is that every requirement references the owning solution.

I think there is a more fundamental issue here having to do with how relationships are represented, or rather how they are not. #401
