/**
 * Tree grid component that can be used to display nested rows of data.
 * Supports filtering and sorting.
 * @stacked-example(Showcase, tree-grid/tree-grid-showcase.component)
 *
 * ### Installation
 *
 * Import `NbTreeGridModule` to your feature module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbTreeGridModule,
 *   ],
 * })
 * export class PageModule { }
 * ```
 *
 * ### Usage
 *
 * As the most basic usage you need to define [nbTreeGridRowDef](docs/components/treegrid/api#nbtreegridrowdefdirective)
 * where you should pass columns to display in rows and
 * [nbTreeGridColumnDef](docs/components/treegrid/api#nbtreegridcolumndefdirective) - component containing cell
 * definitions for each column passed to row definition.
 * @stacked-example(Basic, tree-grid/tree-grid-basic.component)
 *
 * `NbTreeGridComponent`'s source input and `NbTreeGridDataSourceBuilder.create` expecting data to be an array of
 * objects with `data`, `children` and `expanded` properties. If your data doesn't match this interface, you can pass
 * getter functions for each property as arguments to `NbTreeGridDataSourceBuilder.create` method.
 * @stacked-example(Custom node structure, tree-grid/tree-grid-custom-node-structure.component)
 *
 * To use sorting you can add `nbSort` directive to table and subscribe to `sort` method. When user click on header,
 * sort event will be emitted. Event object contain clicked column name and desired sort direction.
 * @stacked-example(Sortable, tree-grid/tree-grid-sortable.component)
 *
 * You can use `Data Source Builder` to create `NbTreeGridDataSource` which would have toggle, sort and
 * filter methods. Then you can call this methods to change sort or toggle rows programmatically. Also `nbSort` and
 * `nbFilterInput` directives both support `NbTreeGridDataSource`, so you can pass it directly as an input and
 * directives will trigger sort, toggle themselves.
 * @stacked-example(Data Source Builder, tree-grid/tree-grid-showcase.component)
 *
 * You can create responsive grid by setting `hideOn` and `showOn` inputs of
 * [nbTreeGridColumnDef](docs/components/tree-grid/api#nbtreegridcolumndefdirective) directive.
 * When viewport reaches specified width grid hides or shows columns.
 * @stacked-example(Responsive columns, tree-grid/tree-grid-responsive.component)
 *
 * To customize sort or row toggle icons you can use `nbSortHeaderIcon` and `nbTreeGridRowToggle` directives
 * respectively. `nbSortHeaderIcon` is a structural directive and it's implicit context set to current direction.
 * Also context has three properties: `isAscending`, `isDescending` and `isNone`.
 * @stacked-example(Custom icons, tree-grid/tree-grid-custom-icons.component)
 *
 * By default, row to toggle happens when user clicks anywhere in the row. Also double click expands row deeply.
 * To disable this you can set `[clickToToggle]="false"` input of `nbTreeGridRow`.
 * @stacked-example(Disable click toggle, tree-grid/tree-grid-disable-click-toggle.component)
