/**
 * HTTPInterface exists to separate the HTTP client implementation from the CCB client.
 *
 * The concern here is that it may not be possible or desirable to take a dependency on the
 * Apache HTTP Client library. If that case arises the CCBAPIClient and the HTTPInterface
 * implementation can be split into separate packages. For simplicity's sake I'm not doing
 * that now. But if it needs to be done at a later time the code will already be isolated.
