attributes may be string (assumes it's a uuid) or an object containing data attributes
function(attributes) {
        if (_.isString(attributes)) { attributes = { uuid: attributes }; } // assume it's a uuid
        var data =_.assign({}, this._usergrid.defaults, attributes);
        data.type = this._usergrid.type;
        return wrap(this, new usergrid_sdk.entity({data: data, client: client}));
      }
