List type should support multi-fields

The list type should support multiple fields, e.g., that way it can be used as a key-value mapping.

Hi Jeremy

I'm not sure if this should be in the list type. Might be more useful to put this in a separate 'dictionary' or 'table' field.
Also, I guess if we start supporting key-value lists, that it should be extendible to have the more generic 'table' field, which supports multiple values?

I agree! Table sounds great.

For reference, Apple WiFi table settings.
