MaybeMultiple

This is a utility crate that establishes an enum to use in place of Option where the content may be singular, multiple (a Vec) or None. It is particularly useful in situations where a JSON object is being deserialized and may take these types of forms:

"https://example.com/id/uuid"

["https://example.com/id/uuid1", "https://example.com/id/uuid2"]

null

These would all match to MaybeMultiple as ::Single, ::Multiple, ::None, respectively.
