<p>This view allows to plot gereferenced documents on a map. The location
information can be provided either via a field with
<a href="http://geojson.org">GeoJSON</a> objects or two fields with latitude and
longitude coordinates.</p>
<p>Initialization arguments are as standard for Dataset Views. State object may
have the following (optional) configuration options:</p>
<pre>
{
// geomField if specified will be used in preference to lat/lon
geomField: {id of field containing geometry in the dataset}
lonField: {id of field containing longitude in the dataset}
latField: {id of field containing latitude in the dataset}
