/**
* 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)
