When the maximum type is float64, using json.Unmarshal(raw, &spec.Swagger{}) will lose precision

When the maximum type is float64, using json.Unmarshal(raw, &spec.Swagger{}) will lose precision

definitions:
  TestResponse:
    description: test
    type: object
    properties:
      test_1:
        description: test_1
        type: long
        format: int64
        **maximum: 9223372036854775807**
        minimum: 0

because

type SchemaProps struct {
	Maximum              *float64         `json:"maximum,omitempty"`
}

@O3cheng yes you're correct: mapping numbers as float64 is not truly JSON compliant (in the sense there is no support for arbitrarily large numbers). On the other hand, we didn't want to manipulate a big.Rat type everywhere we had some numerical input. Trade off.
