You can use Javascript dotted * object notation to get a data source for multiple levels of nesting, or * it my be used as a function.

The function * takes three parameters: * * Parameters: * * `{array|object}` The data source for the row * * `{string}` The type call data requested - this will be 'set' when * setting data or 'filter', 'display', 'type', 'sort' or undefined * when gathering data.
