Describe references as such #345
Description
As mentioned in outmoded/lout#57, references should have their own descriptions.
> Joi.compile(Joi.ref('a.b')).describe()
{ type: 'any',
flags: { allowOnly: true },
valids:
[ undefined,
{ [Function]
isContext: false,
key: 'a.b',
path: [Object],
depth: 2,
root: 'a',
isJoi: true,
toString: [Function] } ],
invalids: [ null ] }I think isContext, key, path, depth, root should be exposed at the root of the description and type should indeed be ref.
