/**
* Tabs can be either pure or stateful. Stateful tabs will keep track of which one is active by keeping an internal
* state.
*
* Pure tabs will only change the active tab when the `activeId` property is updated.
*
* ## Stateful Tabs
* ```html
*
* Optional content here.
*
*
*
* ```
*
* ## Pure Tabs
* ```html
*
*
*
*
*
* ```
*
* ## With `routerLink`
* A gtx-tab can take an optional `[routerLink]` binding which will set router links for the tabs.
* ```html
*
*
*
*
*
* ```
* * ##### Vertical Tabs
* A gtx-tabs can take an optional `vertical` property which allows to display tabs vertically.
* ```html
*
*
*
*
*
* ```
* * * ##### Active Tabs with Icons
* A gtx-tabs can take an optional `hideTitle` property which allows to hide the title for non-active tabs with icons.
* ```html
*
* Tab 1 Content
* Tab 2 Content
*
* ```
