* Defines a set of tabs in a form.
* The tabs are build with our standard tabstrip javascript library.
* By default, the HTML is generated using FieldHolder.
*
* <b>Usage</b>
*
* <code>
* new TabSet(
* $name = "TheTabSetName",
* new Tab(
* $title='Tab one',
* new HeaderField("A header"),
* new LiteralField("Lipsum","Lorem ipsum dolor sit amet enim.")
* ),
* new Tab(
* $title='Tab two',
* new HeaderField("A second header"),
* new LiteralField("Lipsum","Ipsum dolor sit amet enim.")
* )
* )
* </code>
*
* Caution: The form field does not include any JavaScript or CSS when used outside of the CMS context,
* since the required frontend dependencies are included through CMS bundling.
