HttpClientUtil

Use retrieveGetReponse and retrievePostResponse for making any web calls. This will take care of setting up the client.

Use composeURL to combine any components into a URL. This will avoid needing to predict whether a fragment ends with a '/' or not.

Use readListFromResponse or readObjectFromResponse to convert an HttpResponse into a known object type.

Use throwResponseError if a response comes back from a resource with an error, to throw the appropriate exception and pass the message on.
