 ### New Features
 - `IgxGrid`, `IgxTreeGrid`, `IgxHierarchicalGrid`
     - `uniqueColumnValuesStrategy` input is added. This property provides a callback for loading unique column values on demand. If this property is provided, the unique values it generates will be used by the Excel Style Filtering (instead of using the unique values from the data that is bound to the grid).
