code: function extendingEndpoints() {
    var segments = Array.prototype.slice.call(arguments, 0);
    return function () {
      var path = '';
      segments.forEach(function (pathSegment) {
        path = path + pathSegment;
        createEndpointFromPath(path);
        console.log('  registered path %s', path);
      });
    }
  }
docs: Create a thunk that will build up endpoints from an ordered set of path
  segments, registering the endpoints at all stages along the way.
  
  Each endpoint must have a corresponding JSON file in the mocks directory.
