// These are very definitely preliminary. Please feel free to improve.

// Changelog:
// 8/11/2015 ui-grid  v3.0.3
//   Extensive plugin support added (Plugin specific API, ColumnDef, GridOptions, GridRow, Constants).
//   Added docs for all existing interfaces.
//   Fixed a few incorrect interfaces, updated interfaces to reflect latest version.
//   Did some cleanup... Moved all plugins into their own modules
// 7/8/2015 ui-grid v3.0.0-rc.22-482dc67
//   Added primary interfaces for row, column, api, grid, columnDef, and gridOptions.  Needs more tests!

         * Most commonly the data is an array of objects, where each object has a number of attributes.

         *
         * `$scope.data = data;`

         *   $scope.gridOptions.data = $scope.myData;
         *  });`
