Mock specific example in response of specific request!

[Yeganloo]

Hello and thanks for this nice job!
I hope to use prism as mock server to simulate third-party services and cover my integration tests.
In current version of prism, there is no relation between requests and response, so if i have third-party api whit 3 different responses, such as:

• 200 (and a full object)
• 201 (and new record id)
• 202 (and some description)
  There is no way to test all 3 possible scenario!
  I couldn't find any official way in open-api documentation to cover this subject but there are named examples that can help us out. So i defined named request examples an their pair named responses.
  If prism answer the paired response of specific request examples, it will be a grate integration test tool.
