Swagger swagger = Swagger20Parser().parse(swaggerAsString), swagger.getDefinitions() doesn't return those definition which are not object/array type

Below is the version which I have used:

	<dependency>
		<groupId>io.swagger</groupId>
		<artifactId>swagger-inflector</artifactId>
		<version>2.0.0</version>
	</dependency>

Below is the swagger which I have tried. It did not return 'country' as a model.

Start at Swagger20Parser().parse(swaggerAsString) and inspect how getDefinitions() handles the definitions map, especially the string-typed country schema referenced by PaymentSDPData. Reproduce the supplied Swagger document and consider the issue resolved when getDefinitions() includes country as well as PaymentSDPData.
