recursive model definitions causes crash

[sev-g]

version 0.18.1
If you have a model with a recursive property like:

"Person": {
  "required": ["id", "persons"],
  "type": "object",
  "properties": {
    "id": {
      "format": "int64",
      "minimum": 0,
      "exclusiveMinimum": true,
      "minLength": 1,
      "type": "integer",
      "readOnly": true
    },
    "persons": {
      "uniqueItems": false,
      "type": "array",
      "items": {
        "$ref": "#/definitions/Person"
      },
      "readOnly": true
    }
  }
}

then the code generation will crash with:

@SevastianGioanca I'm getting the same failure.

likely to be caused by APIDevTools/json-schema-ref-parser#36 or APIDevTools/json-schema-ref-parser#40

[tmack8001]

In my scenario I wasn't purposefully making an infinite nesting behavior... so I've now split the swagger data types to prevent an indefinite nesting and instead just a 2 layer nesting

[glebmachine]

got the same, with four huge swagger definition files

The exception should be avoided now with #110 . Please see the description in the PR for how to set up to ignore circular references.
