Display a grid reference on the map and an index associated with.

You have to define the <i>extent</i> and the <i>size</i> of the grid.

You can define a <i>ol.source.vector</i> or use the <i>setIndex</i> method to display an index.

<li>
|
|
You can define a <i>property</i> (or a function to retrieve it) that will be displayed in the index.

You can customize a <i>sortFeature</i> function and the <i>indexTitle</i>
