toString :: UUID -> StringSource

Convert a UUID into a hypenated string using lower-case letters. Example: 

  toString $ fromString "550e8400-e29b-41d4-a716-446655440000"
fromString :: String -> Maybe UUIDSource

If the passed in String can be parsed as a UUID, it will be. The hyphens may not be omitted. Example: 

  fromString "c2cc10e1-57d6-4b6f-9899-38d972112d8c"

Hex digits may be upper or lower-case.

null :: [a] -> BoolSource
