The example uses the "cluster#balloonCarousel" cluster balloon layout.
In this layout, information about the geo object is shown in the center, and buttons for going to the previous and next geo objects are shown on the sides.
There is a quick navigation menu in the lower part of the balloon.
The information about the selected geo object is set by a separate layout and can be configured using the 'clusterBalloonItemContentLayout' option.
This example sets a custom layout with information about a geo object.
Layouts for objects can be created using the templateLayoutFactory factory, and using text templates.
Text templates form the HTML content of the layout from a hash with the data passed to the layout constructor.
In this example, the data provider is the geo object.
