title: How to create an API endpoint without a model in Loopback?
body: <p>I understand we can create remote methods on models which will expose an endpoint. However, is there a way to expose an endpoint without a model?</p>
  
  <p>For example, if I want to create an endpoint checks the version of a native app. I don't need a model to back this endpoint. The endpoint would simply check the passed in version and respond. </p>
  
  <p>Does this construct exist within Loopback?  Or does it need to be done within the context of Express? </p>
