Use Accept Headers to GET XML Content as a preference

How to complete the challenge GET /todos XML (200) to successfully GET all the todos in XML format as first preference.

GET /todos XML Preference (200)

It is possible to ask for multiple types in the Accept header, expressing a preference for the returned format. If none of the types are available then expect a 406 response.

Issue a GET request on the /todos end point with an Accept header of application/xml followed by application/json to receive results in XML format if supported, or JSON if not.

GET request will receive a response with all the todo items
- e.g. GET /todos to get all the todo items
200 is a success code, in this case it means the end point exists and the `todo items were returned
Accept means that an Accept header was added to specify that the todos should be returned in XML format as first preference, followed by JSON as second preference
add the X-CHALLENGER header to track progress

Basic Instructions

Issue a GET request to end point "/todos"
- if running locally that endpoint would be
  - http://apichallenges.herokuapp.com/todos
The request should have an Accept header specifying XML format by using a value of application/xml,application/json
The request should have an X-CHALLENGER header to track challenge completion
The response status code should be 200 when all the details are valid.
Check the body of the message has JSON format data, which is the default from the server
Check the content-type header in the response has application/json

The chained Accept header application/xml,application/json asks for XML as first preference, but if not supported then supply JSON.
