// Spec validates a spec document
// It validates the spec json against the json schema for swagger
// and then validates a number of extra rules that can't be expressed in json schema:
//
// 	- definition can't declare a property that's already defined by one of its ancestors
// 	- definition's ancestor can't be a descendant of the same model
// 	- each api path should be non-verbatim (account for path param names) unique per method
// 	- each security reference should contain only unique scopes
// 	- each security scope in a security definition should be unique
// 	- each path parameter should correspond to a parameter placeholder and vice versa
// 	- each referencable defintion must have references
// 	- each definition property listed in the required array must be defined in the properties of the model
// 	- each parameter should have a unique `name` and `type` combination
// 	- each operation should have only 1 parameter of type body
// 	- each reference must point to a valid object
// 	- every default value that is specified must validate against the schema for that property
// 	- items property is required for all schemas/definitions of type `array`
