Enable polymorphism

[nakamorichi]

...by merging members of "allOf" into a single properties object and a single requirements array.

Fixes #29

@Kitanotori Thanks for the contributions here. Are there any unit tests that you can add to ensure that this functionality doesn't undergo regression in the future?

[briananderson1222]

If not, I plan to go back and add some tests for the additionalProperties functionality I added and might be able to take a look at adding tests here. I think with those two change it may warrant a new release.

[nakamorichi]

Unfortunately no time to write tests currently.

This does not handle $ref only members of allOf, does it? Example:

"definitions": {
        "dealer_output": {
            "title": "Dealer Output",
            "allOf": [
                {
                    "$ref": "#/definitions/dealer_input"
                },
                {
                    "type": "object",
                    "properties": {
                        "_id": {
                            "type": "string",
                            "format": "uuid"
                        }
                    },
                    "required": [
                        "_id"
                    ]
                }
            ]
        }

This is what I came up with to solve the problem I mentioned above: celalo@8c4370a

I just saw this! Thanks for pushing forward on these updates! From what I can tell the Travis job is failing due to some nested dependencies that no longer support node 0.11. Feel free to update to 4+ in the travis.yml and see if we can get the tests to pass here.

[nakamorichi]

@briananderson1222 I fixed Travis's and Mocha's settings (timeout limit was too low). Now only the test I added, containing example of allOf definition, fails.

[LGLC]

Line 247 (var required = fullObject.required || [];) should be moved to line 251 (i.e. after processPolymorphic runs if the definition is polymorphic) otherwise we're not adding in the merged required fields.
