I need to render swagger files using POJO classes which reads description of an API from CSV files, and I use your API to get this done. CSV files describes elements from a business point of view and are **not** sorted alphbetically. Example : Property 1 : sub-property B sub-property C sub-property A When I use your lib to generate swagger, here is what I get : Property 1 : sub-property A sub-property B sub-property C As you can see, sub-properties are sorted. Here is my method's code to get yaml string : `return Yaml.pretty().writeValueAsString(factory);` where factory is a io.swagger.models.Swagger instance. Would it be possible not to sort the properties when rendering Yaml ?
