/**
 * **Ignite UI for Angular Tooltip Target** -
 * [Documentation](https://www.infragistics.com/products/ignite-ui-angular/angular/components/tooltip)
 *
 * The Ignite UI for Angular Tooltip Target directive is used to mark an HTML element in the markup as one that has a tooltip.
 * The tooltip target is used in combination with the Ignite UI for Angular Tooltip by assigning the exported tooltip reference to the
 * target's selector property.
 *
 * Example:
 * ```html
 * <button type="button" igxButton [igxTooltipTarget]="tooltipRef">Hover me</button>
 * <span #tooltipRef="tooltip" igxTooltip>Hello there, I am a tooltip!</span>
 * ```
