/**
 *
 * Tooltip directive for small text/icon hints.
 *
 * ### Installation
 *
 * Import `NbTooltipModule` to your feature module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbTooltipModule,
 *   ],
 * })
 * export class PageModule { }
 * ```
 * ### Usage
 *
 * @stacked-example(Showcase, tooltip/tooltip-showcase.component)
 *
 * Tooltip can accept a hint text and/or an icon:
 * @stacked-example(With Icon, tooltip/tooltip-with-icon.component)
 *
 * Same way as Popover, tooltip can accept placement position with `nbTooltipPlacement` property:
 * @stacked-example(Placements, tooltip/tooltip-placements.component)
 *
 * It is also possible to specify tooltip color using `nbTooltipStatus` property:
 * @stacked-example(Colored Tooltips, tooltip/tooltip-colors.component)
 *
 * Tooltip has a number of triggers which provides an ability to show and hide the component in different ways:
 *
 * - Click mode shows the component when a user clicks on the host element and hides when the user clicks
 * somewhere on the document outside the component.
 * - Hint provides capability to show the component when the user hovers over the host element
 * and hide when the user hovers out of the host.
 * - Hover works like hint mode with one exception - when the user moves mouse from host element to
 * the container element the component remains open, so that it is possible to interact with it content.
 * - Focus mode is applied when user focuses the element.
 * - Noop mode - the component won't react to the user interaction.
