Add beginnings of validator class.
Finished implementing validation, but still needs testing.
Add validator support for dependencies, disallow, and extends.
Fixed bugs and typos in validator.
Add test script which tests the validator against every validation keyword.
Add null editor.
Remove `isValid` methods from all editors and replaced the `validate` api call to use the new Validator class instead.
Change example to automatically validate on change and display the results instead of requiring a button click.
Add support for type="any" in the multiple editor.
Add support for arrays without `items` defined and objects without `properties` defined.
Add support for the `required` attribute from version 3 of the spec.
Restructured readme to be more user friendly and logically laid out.
Fix typo with version 3's `require` keyword.
Add optional parameter to validate api call that lets you pass in data to validate.
Made the Validator class self contained.
Now, JSON Editor fully resolves all references before initialization.
Added more validation test cases for $ref and definitions.
Cleaned up the code.
