// I needed to redefine the remap() function invoked at
// https://github.com/APIDevTools/json-schema-ref-parser/blob/master/lib/bundle.js#L25 due to
// https://github.com/APIDevTools/swagger-parser/issues/127
// 
// I'm not versed enough with JavaScript and Node.js to understand if there would be a less invasive way to have my own 
// remap(). As far as I understand SwaggerParser (or JSON Schema $Ref Parser for that matter) is not built in a way that
// allows to easily extend it. The only option I found was to redefine the bundle() prototype function and to copy a lot
// of code from bundle.js.
